Deep-water divers built around one obsession: legibility at depth.
For iPhone · iOS 26.5 or later
Your iPhone,
reimagined as a
mechanical watch.
ChronoSet is a composition engine for watch faces — every dial, colour, hand, bezel and complication is a choice you get to make.
Coming soon to iPhone
The collection
Five faces. Each in light and dark.
Toggle the theme (top right) and the whole page — including these faces — switches between day and glowing night.
Diver
60-minute dive bezel, full lume
Sport
Steel case ring, date & power reserve
Chronograph
Working stopwatch, slide-rule bezel
GMT
Second time zone, day/night bezel
Dress
Dauphine hands, moon phase, calendar
The engine
Composition, not presets.
Nothing on a ChronoSet face is baked in. Choose a face, then reshape it — the defaults are only a starting point.
Deep customisation
Dial colours & finishes, hand shapes & metals, hour and minute markers, bezel designs, and dual lume — mixed and matched per face.
Real complications
Mechanical moon phase, battery power reserve, pointer date, and an aviation-style slide-rule bezel on the chronograph.
Digital & Set Time
An optional retro seven-segment readout below the dial shows live time — or the exact minute to set a real watch to.
Lume that glows
Primary and secondary lume light up as the watch darkens. A Darkness Level lets night mode go from dusk to pitch black.
Tuned to feel real
Selectable beat rate, detented bezel rotation with haptics, a gyro-reactive sapphire crystal, and a countdown timer with beeps.
Desk Stand Mode
While charging and stationary, ChronoSet fades away the controls, holds the display awake and leaves the watch face on black after one minute.
Go further
More craft. More complication.
The same five faces, pushed further with configurations made possible by the optional premium packs.
Diver
Premium bezel treatments, crafted handsets, expanded lume and material choices give the tool-watch format a more individual character.
Sport
Premium dial finishes, marker styles, hand materials and complications turn the clean sports layout into a much richer composition.
Chronograph
Slide rule, premium sub-dial finishes, expressive hands, materials and high-beat motion bring out the full instrument-watch character.
GMT
Additional GMT colourways, bezel treatments, premium dials and handsets make the second-time-zone face much more expressive.
Dress
Moon phase, pointer date, premium metals, dial finishes and typography give the Dress face its most elaborate configurations.
Display Time
Your desk’s daily driver.
While your iPhone is charging, you can use Widgets to display any of the five watch dials in StandBy mode, or when you leave the ChronoSet app running it will display the dial using its own Desk Stand Mode.
| Feature | iOS StandBy | Desk Stand Mode |
|---|---|---|
| Security | Phone is locked | Phone is unlocked |
| Appearance | Dark | Light or Dark |
| Time Display | Hours, Minutes | Hours, Minutes, Seconds |
Signature Collection
Five original marques. Yours from the start.
ChronoSet includes five fictional watch houses created for the app. Their logos are free for everyone and show how a dial changes when it carries a distinct identity.
Understated English dress watches, in the maison tradition since 1911.
Cartography-inspired GMT and world-timer watches for the frequent traveller.
Rugged field and pilot tool watches, sharp-eyed and built to take a knock.
Motorsport chronographs measuring life in thirds of a second.
Use the mark, the name, or both — in the brand artwork or rendered monochrome to match the dial.
Built with accessibility in mind — VoiceOver reads the time aloud, and the app’s animations follow your Reduce Motion setting.
Pricing
A generous free core. Two optional packs.
Every face type, and enough dials, hands, markers and complications to build watches you'll love, are free. Go deeper with a one-time unlock — no subscription.
