Use this horology calculation to interpret a stated watch, clock, timing-machine, water-resistance, alarm, or historical respiratory-timing quantity under its defined convention.

Disc Positions

Required integer input.

Cycle Minutes (min)

Required number input.

Flip-disc advances per minute from total disc positions and one complete cycle duration. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Advances Per Minute (1/min)

The resulting advances per minute returned as a number.

• Mechanical-watch amplitude and beat measurements depend on lift angle, position, state of wind, movement condition, instrument setup, and elapsed sampling. ATM markings are test-pressure classifications rather than literal safe diving depths.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Confirm movement specifications and measure in multiple positions and power states; follow the manufacturer's water-resistance guidance and obtain pressure testing after case service.

• Day Disc Advance Rate

  Day-disc angular advance in degrees per daily step for a specified number of disc positions.

• Moonphase Gear Ratio

  Display-cycle days from moon-disc tooth count and tooth advances per day.

• Asthmometer Breath Rate

  Breaths per minute from a counted number of breaths and elapsed seconds.
