Emerald Chronometer®
Wear OS by Google


Emerald Chronometer® is a collection of 21 faces for Wear OS by Google (previously known as Android Wear) that model high-end mechanical watches. (It's also an Apple iPad app, and an Apple iPhone app that was one of the first apps in the Apple App Store in 2008).

These faces contain many of the most complex "complications" found in real watches, plus refinements found nowhere else. All displays maintain the look and feel of real mechanical objects, but with the time and location accuracy of the connected phone.

Time and date features:

Astronomy features:

There are two versions of Emerald Chronometer for Wear OS:

Get it on Google Play A paid app with all of the faces included (Emerald Chronometer)
Get it on Google Play A free demonstration app (Emerald Chronometer FREE) with in-app purchases.

The FREE app includes only the DEMO face, but the other faces may be purchased either individually or all at once with in-app purchases; the DEMO face cycles through all the other faces, running time at high speed to demonstrate how the displays work.

In addition; all of the faces are avaiable for purchase separately; see the How to Buy page or the "Get it on Google Play" button on each face description page (linked below).

(If you like Emerald Chronometer but you wish you could change the displays yourself to times in the past or future, you might be interested in Emerald Chronometer for the iPhone or iPad, which have this feature).
