CERAMIC BEZEL NOW SOLD OUT

The possibility of a mission timer was first discussed on the forum in 2007. At that time, the movement I wanted to use had been discontinued by ETA and I didn’t know enough about the successor. By the time I decided to proceed, the chosen movement (ETA 251.264 BD) was not a stock item with ETA, movements were manufactured to order with a long lead time. The BD suffix means that the movement incorporates PreciDrive and PowerDrive technologies with a typical accuracy of +/- 10 seconds per annum.

What Are Mission Timers?

A Mission Timer is a watch concept that Sinn evolved in the late 1990s, specifically in the EZM1. The concept is very simple. It needs to tell the time; it needs to measure elapsed time and it needs a bezel. And it must do all these things with utmost clarity, in every situation, so simplicity is key to the dial. Not to mention the case design must also consider hand combination, durability and water resistance.

Whilst the ETA 251.264 is capable of being a 3 register chronograph, the sub-dials on the Precista Mission Timer are not used to keep the dial very legible, only the running seconds (at 12), chronograph seconds hand and chronograph 60 minute recorder (the aeroplane tipped hand) are used in addition to the hour and minute hand.

How to use a Mission Timer

The chronograph is operated by means of pushers A and B. The measurement starts when button A is pressed once and then stopped when pressed again. Press B to reset the chronograph to the zero position.

It is possible to also measure split/lap times by pressing A to start the chronograph then pressing B to temporarily pause the hands, after pressing B again the hands will jump to the elapsed time since pusher A was first pressed. Pressing A to fully stop the chronograph then B will reset the hands to zero.

Using the bezel to measure time

The bezel can be moved manually anti-clockwise. It can be used in a number of ways, including to measure important lengths of time. For example, you can set the marking to the beginning of the time span to be measured, or you can use it to indicate the end of a given span of time. The bezel triangle and numbers are luminous.
