question on date window and clasp

[glimmer]

Hi,

Just a question about the double date windows on the Cockpit. The numbers on both windows aren't exactly aligned and I'm wondering if this is normal or perhaps it may need some regulating.

On the inner lock of the clasp, the AD told me that the best way to lock it is to slide it in with pressure exerted upwards instead of on the clasp itself, the same goes for removing it, "in order not to damage my fingernails." Is this a common Breitling experience? I asked if this applied to my wife's Colt as well and she said yes.

Any inputs would be most welcome.

Thanks

I think in an ideal world the double windows would line up perfectly but as a working part they are eventually going to have some "play" in them which has the potential to get them out of whack a bit.

I'm not sure about locking the clasp but it is much easier to exert pressure upwards to remove the clasp.

Thank you Todd, I thought the same quite as much, thank you for verifying this. Though I was wondering how sturdy or vulnerable the Caliber 49 (i think) is, given this extra complication. Would you know if there are certain no-nos in setting the date with regards to the time?

Hi glimmer,

The rule of thumb when setting the date is avoid the hours between 8pm and 2am.
During this window the date change mech is engaged with by the movement. The date can be rolled over by moving the hands through the remaining hours. If you use the date change detent (first pulled out position of the stem and crown) you might put the gears/cams out of sync and cause problems for yourself. I prefer to adjust the date when required the following day first thing in the morning. Good light, clear head, and nimble fingers :-) makes for a quick job. Add a few turns of the stem to the main spring for good luck and on with the day.

SnapIT---thank you for this. Though I knew the rule of thumb I didn't realize until now that the date mechanism is engaged/geared with the time mechanism from 8pm to 2am, thus the need to avoid auto changing the date during that period. Duh...I should've figured that out a long time ago...well, the more you find out, the less...

Thanks, and I'll try some of those good luck turns...
