Re: Chrono question

In Response To: Chrono question ()

: When I use the chrono function on my Speedmaster does it
: effect the accuracy of the movement? For example, does
: using the chrono put an extra 'draw' on the rest of the
: watch causing it to keep less accurate time?

There is an extra draw, but if the movement is OK, you won't notice it. Every month or so I let the chrono function running for 12 hours to evenly spread oil on the 12 hour gear, and I didn't notice a loss in accuracy.

: Also, does using the chrono reduce the power reserve?

Yes, but not in the battery sense. As the resistence to run is increased by the extra train of gears the chrono adds to the movement the mainspring is powering, the watch could stop before the whole mainspring is unwound. You can try it by fully wind the watch and measuring the power reserve with and without the chrono running.

: I haven't noticed any problems, just curious.

As watchnuts tend to be...

Best regards.
