About The Rotation. Watch Collection
Measure a mechanical watch's accuracy with the iPhone's microphone, keep your collection on record, and log what you wear. The Rotation keeps one accurate record of a watch collection: references, serial numbers, photographs, what was paid, what it is worth, when it was serviced, and every day it spent on the wrist. The record a claim or an executor asks for, kept properly, and kept to yourself. THE REGISTER File a watch from its photograph or by hand. Serial numbers stay in the register and never appear on a card. A daily wear log answers the question a collection quietly asks — what actually gets worn, and what has not left the drawer since spring. A wishlist keeps the watches you are hunting, in your order, with money put by towards the next. THE TIMEGRAPHER The phone's microphone is an instrument. Hold a mechanical watch to it and the app reads its rate in seconds a day, its beat error, and its beat rate, then files the reading against that watch. It settles on an answer or it refuses; it will not report a rate it cannot hear. Readings build a bench record over time. A guided compass check of about thirty seconds says whether a watch is magnetised. THE OBSERVATORY Your collection ranked at the bench, as the observatories once ranked them, on the median of each watch's last three readings. Each piece is placed against COSC, METAS, or its own order of accuracy, and its bench record charts its rate over the weeks. THE ROTATION REPORT A monthly account of the collection, set like a page rather than a dashboard: what you wore, what stayed in the box, what moved in value, and what falls due. Nothing is sent to you. It waits. THE REGISTRAR An assistant that answers about your own register and nothing else, and that can file a watch, log a day's wear or record a service when you ask it to. It proposes; you confirm. Identification from a photograph proposes a reference and says why, and declines when the evidence does not support one. WHAT IT IS NOT It is not a marketplace. Nothing is listed, nothing is brokered, no commission exists, and we earn nothing when you buy or sell a watch. It is not an authentication service. Identification proposes a reference; it never certifies that a watch is genuine. It is not a valuation service. A value in your register is an estimate: your own, or one the Registrar proposes from public prices for you to accept or change. Nothing here is an appraisal, an insurance valuation, or financial advice. PRIVACY Your register is yours. It is not sold, not shared with advertisers, and not used to train anything. There are no adverts and no trackers. Audio from the bench is analysed on the device. A take you choose to keep is filed with the reading, so the watch can be heard again from its record. Three watches are kept free, with their photographs, their wear log, the bench and the compass, and their copy on every phone you sign in on. Reading and exporting your register stay free, member or not. Membership pays for what costs us something to run: the whole collection past three watches, the bench’s voices, the Registrar, the importer, the wishlist’s photographs, and identification on the wishlist and past the free daily allowance. — Membership is an auto-renewing subscription.

What’s new
Version 1.1.6 · Updated October 22, 2026
Choose a photo you already have opens your library on iOS 27. Apple's photo picker could stand on "Loading…" there while your photographs were being mounted; it no longer does, and the Mounted style now shows on iOS 27 too, with a watch worn on the wrist framed square on its case. A watch is filed under its house as your collection spells it. An IWC whose dial reads "IWC SCHAFFHAUSEN", or a Bulgari whose dial reads "BVLGARI", stands with the IWC or Bulgari already in your register, however the Eye settles the reading. Camera, Choose and Remove beside a wish's photograph are as easy to tap as the watch form's. A bench reading's Filed time stays the time it was filed. Smaller corrections throughout.
