Smart watches where digital meets traditional.

Apple Watch Ultra, Garmin Fenix, TAG Heuer Connected, and the hybrid pieces that try to bridge mechanical and digital. The category Apple built and the Swiss are still figuring out.

What is a smart watch?

A smart watch is a wristwatch with embedded digital electronics — typically a touchscreen display, processor, sensors (heart rate, accelerometer, GPS, blood oxygen, ECG), and connectivity (Bluetooth, Wi-Fi, cellular). Apple Watch dominates the category with over 50% global market share by units. Garmin leads serious-athlete and military markets. TAG Heuer Connected is the only major luxury Swiss smartwatch with Wear OS support. Hybrid smart watches combine mechanical movements with limited digital features.

What a smartwatch is in 2026

The smart-watch category was effectively created by Apple in April 2015 with the original Apple Watch. Earlier attempts (Pebble 2013, Samsung Gear S 2014, Motorola Moto 360 2014) had pieces of the formula but lacked the integration, ecosystem, and design quality to drive mainstream adoption. The Apple Watch came with the iPhone integration, the App Store ecosystem, and the Apple brand recognition that no previous smart watch could match.

Eleven years later, the smart-watch category ships approximately 50 million units per year — three times the entire Swiss watch industry by units sold. Apple Watch holds approximately 50% global market share by units, with Samsung (~9%) and Garmin (~8%) the closest competitors. The category fragmented into three subcategories: general-purpose smart watches (Apple Watch, Samsung Galaxy Watch, Google Pixel Watch), serious-athlete and military smart watches (Garmin Fenix, Garmin Forerunner, COROS, Suunto), and luxury smart watches (TAG Heuer Connected — and effectively no others, as the Swiss luxury industry has not built smart-watch infrastructure to compete with Silicon Valley).

The functional capability of modern smart watches significantly exceeds mechanical watches in any feature except aesthetic permanence. Heart rate monitoring, ECG, blood oxygen tracking, sleep analysis, GPS turn-by-turn navigation, contactless payment, message notifications, fall detection, emergency SOS, fitness tracking, music playback, voice assistant — all standard. The Apple Watch Ultra 2 specifically meets MIL-STD-810H construction standards and exceeds the durability of most $5,000 Swiss watches in objective testing. Smart watches are not weaker watches than mechanical Swiss; they are different watches with different priorities.

Apple Watch dominance and the alternatives

The structural fact of the smart-watch market is Apple Watch dominance. By units sold, Apple Watch has held the largest market share continuously since 2015 with no signs of being unseated. The reasons are ecosystem (iPhone integration is structurally tighter than any Android-Wear OS pairing can achieve), software-update support (Apple supports Apple Watch hardware for 4–5 years from release with regular feature updates, exceeding Wear OS), and brand recognition (the Apple Watch is the watch most Americans recognize on sight, exceeding even the Submariner in non-watch-enthusiast recognition).

The alternatives serve specific buyer segments rather than competing across the board. Garmin Fenix and Forerunner are the serious-athlete choice — multi- week battery life, GPS-track recording, multisport profiling, training-load metrics, and ruggedized construction. Garmin owns the running, cycling, and hiking communities the way Apple Watch owns the general-fitness community. The Garmin Fenix 8 ($999–$1,299) and Forerunner 965 ($599) are the most-recommended smart watches for any user whose primary use case is athletic training rather than general lifestyle tracking.

Samsung Galaxy Watch is the Android equivalent of Apple Watch — same general-purpose feature set, integration with Samsung Galaxy ecosystem, and Wear OS software. The Pixel Watch (2022, now Pixel Watch 3) brought Google into the category with deeper Wear OS integration but smaller market share. For Android users who want the Apple Watch experience, the Galaxy Watch and Pixel Watch are the most-recommended alternatives.

The luxury Swiss smartwatch category exists almost entirely as TAG Heuer Connected ($1,800–$2,500). The Connected runs Wear OS in a 45mm sapphire- crystal case with TAG Heuer branding and Caliber E5 (the internal designation for the smart-watch electronics package). Other Swiss makers — Montblanc, Frederique Constant — have launched smart-watch attempts that did not achieve commercial traction. The Swiss watch industry has structurally not invested in smart-watch infrastructure, and the result is a luxury smart-watch category that exists almost exclusively for buyers who specifically want a Swiss brand on a Wear OS smartwatch.

The smart watch and the mechanical watch don't compete. They coexist. Most modern serious enthusiasts own both — the Apple Watch Ultra for fitness, travel, and daily activity tracking; the mechanical for everyday wear and dressier occasions. The wrist alternates by occasion.

Smart vs hybrid vs traditional

Three categories of digitally-augmented watch exist, in decreasing order of digital integration:

Full smart watches. Apple Watch Ultra ($799), Garmin Fenix 8 ($999), TAG Heuer Connected ($1,800), Samsung Galaxy Watch Ultra ($649). Full touchscreen displays, full operating systems, app ecosystems, daily charging required (or weekly for Garmin). The defining trade-off: complete digital capability vs daily charging and 4–6 year hardware lifespan.

Hybrid smart watches. Frederique Constant Hybrid Manufacture ($3,500), Mondaine Helvetica Smart ($595), Withings ScanWatch ($299–$499). A mechanical or analog movement with embedded digital features (activity tracking, sleep analysis, ECG on premium models). Multi-month battery life on the analog display with periodic charging required only for the digital features. The defining trade-off: limited digital capability with mechanical aesthetic and battery life.

Connected mechanical watches. Most are limited editions or concept pieces — Bulgari Octo Finissimo with NFC, Hublot Big Bang e (a full-smart watch with Hublot styling), various special-edition mechanical watches with Bluetooth pairing for setting via app. The category is small and mostly experimental. The defining trade-off: novelty over functional advantage.

The hybrid category is interesting but commercially small. Most buyers want either a full smart watch (for the digital features) or a mechanical watch (for the aesthetic and emotional reasons). Hybrids satisfy a small niche of buyers who specifically want both — and that niche is too small to drive significant production volume from the major Swiss makers.

Watch enthusiasts and smartwatches

The traditional watch community — Hodinkee, Worn & Wound, A Collected Man, the major auction houses, the established watch press — was historically dismissive of smart watches as "not real watches." The Apple Watch was framed as a fashion piece, an electronic accessory, a thing that happens to be worn on the wrist but isn't a watch in the meaningful sense. That cultural position has softened significantly since the Apple Watch Ultra (2022) and the Ultra 2 (2023) demonstrated genuine durability, professional tool-watch capability, and design integrity that earlier Apple Watch models lacked.

Most modern serious watch enthusiasts now own both — and own them without embarrassment. The Apple Watch Ultra is the watch on the wrist for fitness, travel, daily activity tracking, and any context where the smart features specifically matter. The mechanical watch is the watch on the wrist for everyday wear, dressier occasions, weekend outings, and any context where the cultural and emotional pleasure of mechanical horology matters. The two categories don't compete; they coexist in the rotation. The cultural shift from "smart watches aren't real watches" to "smart watches and mechanical watches are different things that work together" has been gradual but is now nearly complete in the serious-enthusiast community.

How to choose

The choice between specific smart watches comes down to operating-system ecosystem and primary use case:

  • iPhone user, general lifestyle. Apple Watch Series 10 ($399) or Apple Watch Ultra 2 ($799). The Series 10 covers all general lifestyle use cases at lower price; the Ultra 2 adds 49mm titanium case, sapphire crystal, MIL-STD-810H ruggedization, and 36-hour battery life for users who want the tool-watch durability.
  • Android user, general lifestyle. Samsung Galaxy Watch Ultra ($649) or Google Pixel Watch 3 ($349). Samsung integrates better with Galaxy phones; Pixel Watch integrates better with Pixel phones; both run Wear OS and access the same app ecosystem.
  • Serious athlete or outdoors user.Garmin Fenix 8 ($999–$1,299) for multisport with multi-week battery life; Garmin Forerunner 965 ($599) for runners specifically; Garmin Instinct 3 ($349) for the budget-rugged option. Garmin's training-load and recovery metrics are deeper than Apple Watch's, which matters for users actually training rather than just tracking activity.
  • Luxury smartwatch identity. TAG Heuer Connected Calibre E5 ($1,800–$2,500). The only major luxury Swiss smartwatch. Buy because you want a TAG Heuer that happens to be a smart watch, not because the smart-watch features specifically justify the premium.
  • Hybrid mechanical-smart. Withings ScanWatch ($299–$499) for the medical-grade monitoring (ECG, blood oxygen) at low price; Frederique Constant Hybrid Manufacture ($3,500) for the mechanical-movement option. Niche category, small production, recommended only for buyers who specifically want the hybrid combination.

Frequently Asked

On smart watches

Should I buy a smart watch or a mechanical watch?

Different propositions, both valid. Smart watches (Apple Watch, Garmin, TAG Heuer Connected) offer fitness tracking, notifications, GPS, payment, continuous software updates, and biometric monitoring (heart rate, blood oxygen, ECG, sleep) — but require daily charging and lose value over years as software ages. Mechanical watches offer aesthetic permanence, no charging requirement, multi-decade lifespan, and the cultural and emotional pleasure of mechanical horology — but provide no smart features. Many enthusiasts own both: an Apple Watch Ultra for fitness, travel, and daily activity tracking; a mechanical watch for daily wear and dressier occasions. The two categories don't compete — they coexist on the wrist (or in the rotation) for different purposes.

Is the Apple Watch Ultra a "real" watch?

Yes — by every functional criterion. The Apple Watch Ultra 2 (49mm titanium case, 100m water resistance, sapphire crystal, MIL-STD-810H construction with operating temperature range -20°C to +55°C) exceeds the build quality of most $5,000 Swiss watches. The Apple Watch is the most-purchased watch in the world by units sold — Apple ships more watches per quarter (~12 million) than the entire Swiss watch industry produces in a year (~16 million units). The Ultra is the model that established Apple as a serious tool-watch maker. The cultural debate about "real watches" predates the Ultra and is mostly aesthetic preference rather than functional argument. A mechanical watch is real because of what it represents culturally; an Apple Watch is real because of what it does functionally. Both are real watches.

What about hybrid smart watches?

Hybrid smart watches (mechanical movement plus limited digital features) occupy a niche. Examples: Frederique Constant Hybrid Manufacture ($3,500 — mechanical FC-750 movement with activity tracking via vibration sensor and small dial-edge MotionX display), Mondaine Helvetica Smart ($595 — mechanical look with hidden smart features and 6-month battery life on the analog display), Withings ScanWatch ($299–$499 — hybrid with ECG, blood oxygen, and 30-day battery), and various older Frederique Constant and Alpina hybrid pieces. The category never achieved mainstream traction — most buyers either want a full mechanical watch or a full smart watch. Hybrids are interesting niche pieces but not commonly recommended as primary purchases.

Are TAG Heuer Connected watches worth the price?

Depends on the alternative. The TAG Heuer Connected Calibre E5 ($1,800–$2,500) is the only major luxury Swiss smart watch with full Wear OS support. Compared to Apple Watch Ultra 2 ($799), the TAG Heuer Connected costs more and offers Wear OS (broader app compatibility outside the Apple ecosystem), sapphire crystal vs Apple's Ion-X glass on lower variants, and TAG Heuer brand prestige. For Android users who want luxury smart-watch identity, the TAG Heuer Connected is the most-defensible choice. For iOS users, the Apple Watch Ultra 2 offers more functionality at lower price. Neither watch is mechanically interesting — both are smart watches with luxury packaging.

How long does a smart watch last?

Smart watches have two lifespans that often differ: hardware and software. Apple Watch hardware typically lasts 4-6 years (battery health degrades to ~80% by year 3, replacement battery service runs $99 in-program). Apple software support lasts 4-5 years from release — the Apple Watch Series 4 (2018) lost watchOS support in 2024. Garmin Fenix hardware lasts longer (5-7 years typical) but has fewer software updates over the watch's life. TAG Heuer Connected is on Wear OS — software lifecycle depends on Google's Wear OS support, which has historically been weaker than Apple's. By contrast, mechanical watches have hardware lifespans of 50+ years with periodic service and no software dependency at all.

What's the cultural divide between smart-watch buyers and mechanical-watch enthusiasts?

It's narrowing. The traditional watch community (Hodinkee, Worn & Wound, A Collected Man, the major auction houses) was historically dismissive of smart watches as not-real-watches. That position has softened significantly since the Apple Watch Ultra (2022) and the Apple Watch Ultra 2 (2023) demonstrated genuine durability and tool-watch capability. Most modern serious watch enthusiasts now wear an Apple Watch (or equivalent) for fitness and travel and a mechanical watch for daily wear and dressier occasions. The cultural divide has shifted from "smart watches aren't real watches" to "smart watches and mechanical watches are different categories that coexist on the wrist."

What is Subdial?

Subdial is an editorial publication covering luxury watchmaking — Swiss heritage houses, dive watches, vintage timepieces, and the makers worth knowing. Coverage includes Rolex, Patek Philippe, Audemars Piguet, Vacheron Constantin, Omega, Tudor, and dozens more. Editorial focus: history, signature collections, what to look for when buying, and how value holds.

Which Swiss watch brands are the most prestigious?

The "Holy Trinity" of Swiss watchmaking is Patek Philippe (founded 1839), Audemars Piguet (1875), and Vacheron Constantin (1755) — the three houses widely considered the apex of haute horlogerie. Rolex is the most recognized worldwide; Jaeger-LeCoultre supplies movements to many top brands; Blancpain is the oldest continuously operating watchmaker (founded 1735). Independent makers like F.P. Journe and Richard Mille operate at the same tier with smaller production runs.

What makes a watch "Swiss made"?

Swiss law requires that a watch labeled "Swiss made" must have its movement assembled in Switzerland, its movement cased in Switzerland, undergone final inspection by the manufacturer in Switzerland, and have at least 60% of its production cost incurred in Switzerland. The standard is enforced by the Federal Council and the Federation of the Swiss Watch Industry FH.
