dv8 1 Posted March 23, 2014 Do original daytona movements have the same problem or is the movement much more reliable? Share this post Link to post Share on other sites
Frankt8242 1 Posted March 24, 2014 (edited) Do original daytona movements have the same problem or is the movement much more reliable? The older ones, (20th century). are modified(to change beat rate) Zenith "El Primero" movements and are very "special".....The more recent ones, after 2000, (sec's at 6:00) are Rolex OEM movements...and they are "special" too...Reliability isn't even an issue with them!!...Just price!!! :giggle: Edited March 24, 2014 by Frankt8242 Share this post Link to post Share on other sites
greg_r 84 Posted March 24, 2014 Now one thing to note that this watch does not have a chronograph function, just the seconds at 9. I'm guessing that this config is far more stable. Yep - they're a lot more robust in that configuration. Share this post Link to post Share on other sites

reximda 0 Posted March 25, 2014 Use my PAM 299 as daily beater and it's been fine. ^^^^^^^ This! Share this post Link to post Share on other sites

Daywatch 4 Posted March 25, 2014 Luckily until now no problems with secs at 9 movements and use them a lot - for about 3 month only. Anyway You start to notice they "seem" more fragile and start treating them with more "care" which is not always comfortable. Hence my best secs at 9 is a robust, tough PAM193 but that one´s got a 23j movement. My 7750 end up being used 1-2 a week, daily beaters are non-chrono autos or quartz chronos (with or without running seconds - these are shockproof) - if I have the chrono function I want to use it, mostly for count-down timing, luckily the rollie-subs do the same to the minute.

myaz 3 Posted March 25, 2014 The movement should survive daily wear. The chrono is what you can't use more than once a month Does using the chrono wear out something prematurely ? Is it to do with the push buttons or other gearing? Pushing the chrono buttons engage extra gears that are normally stationary. These gears are on an added stackable module that doesn't have jewels and introduces extra friction.

Cannibal 0 Posted March 25, 2014 I've had mostly good luck with the A7750. I had it in a PAM194 (so not a chrono) and it ran reliably for about two years until I sold it recently. It's running strong in the PAM243 I got a month ago as well. I also had one in a PAM Daylight that I had for a couple of years. Granted the watch only was worn a handful of times but it worked great. However... Just before xmas 2013 I got a IWC Cousteau chrono (2008 model) and it ran great for a week, until the day wheel got jammed. With a bit of careful jiggling, I got it loose but this is where the problem started. From about 2 a.m. until about 10:30 pm the watch would run fantastically well. Very accurate indeed. But once it got into the date change time frame, the movement ran fine enough, but the jammed date wheel must have snagged something because the watch would lose about 4 hours overnight. It sat for about a week and a half recently while I was out of town and since then, the few times I've worn it, it now loses about 5 minutes per hour, plus the 4 hour loss overnight. I really really like this watch, so I bought a swiss 7750 movement for it and will have it installed shortly. When they run issue free, they're awesome. But when an issue pops up, it's a PITA.

Is it to do with the push buttons or other gearing? sorry for the late answer, in addition to what the others told you about the gears, in my case the part which failed was a thin lever that is pushed by the pusher. Didn't affect the time telling though. Share this post Link to post Share on other sites

What about the same quiestion, only a SERVICED A7750 for daily beater? Share this post Link to post Share on other sites
graman 2 Posted March 27, 2014 I've killed a couple and had success with a couple. Have had 3 that I've worn daily for years. No major dramas. Luck of the draw, but treat it nicely. Share this post Link to post Share on other sites
