Power resvere of Daytona

Hi

How long should a Daytona last?

It is the zenith movement.

I am lucky to get > 24 hrs.

thanks

It's around 50 hours, I believe

Ooh :-( Looks like it needs a service - I get ± 23hrs.

You should get more than 50 hours with the chrono running. Try winding it with the crown from fully unwound forty to fifty times, leave it unworn and see how it goes from there.

For the Zenith Daytona movement the power reserve figures are 54 hours without the chrono going and 47 with the chrono going.
For the latest cal 4130 movement the figures are 72 and 66 respectively.

Ahhh ... I only wind it about 10 times.

The chrono is always running.

Would skydiving kill the watch? Seems a lot less reliable than it used to be.

I do about 200 jumps a year.

thanks

Only if you land on it.

I meant to say 50+ hrs without the chrono running - with it running knocks around 10% off the reserve.

When you say less reliable, what kind of symptoms are you experiencing (other than reduced power reserve)? Impacts can jar the regulation of the watch, making it run fast or slow, or even break a component, but we're talking fairly substantial knocks here! Skydiving shouldn't give you any problems!
