Timegrapher X

The speed of a mechanical wrist watch is not constant. It fluctuates with build quality, watch position, mainspring tension and even temperature. The Timegrapher X iOS app is a unique tool that helps you find, observe and understand patterns developing over time.

Public beta coming soon. If interested in early access, please . Ideal candidates would have basic knowledge of mechanical watches, own variety of watch/caliber types and be willing to send audio recordings of watch beat noises for tests ;)
