44mm/21j auto/bracelet/saphire...Does this exist?

[fastlaw]

I'm basically looking for the 299, which is a 44mm automatic with the bracelet (maybe the 40mm if the 44 isn't available). I want the 21j auto movement with the steel bracelet and saphire crystal. Does this exist, or do I have to get the 7750 movement to get this combo? I'd rather avoid the 7750 after seeing the thread about how they blow up! I've emailed a couple trusted dealers and they are giving me different answers. I got a price of $150 from one dealer, but I have a feeling the watch has a mineral crystal. Thanks

This is basically what I am looking for, but another dealer said that this does not have a saphire crystal: http://www.timeshops.net/PA9423_-_P...al_SS_40MM_-_Asian_21J_Automatic_020005-4.htm

7750 movements are bad when its in a chrono type watch. As long as you dont set the date between 10-2 you should be good.

As Coldi stated, you should be ok with a 7750 for this type of watch. They tend to have issues when you modify them to run seconds at six o'clock. I have a "few" PAM's with 7750 movements and they have been fine. As far as the watch, Timeshops (Mark) is offering, I would email them and confirm if the crystal is synthetic sapphire as listed.

we have these but by the time you add sapphire the price is not that much cheaper than the 7750 watch

I've never heard of a 7750 blowing up...

I've wanted to blowup one or two, but that was because it had a "shiny purple" dial attached to it.

I've got over 20 44mm PAMs with the A7750 movement, only 2 have given me problems. One of those had the GMT module on it, and arrived with the problem, which magically fixed itself a week later. The other problem was due to my "tinkering", resulting in an F'd up keyless.

All the others are ticking away, not sure of their accuracy though, as I don't wear all of them on a regular basis.

I will say that one thing I do now upon receiving a new rep (A7750 or 6497), is open the back, use a squeezable air blower to rid the insides of any visible debris, ensure no screws are loose or missing, put some Moebius oil in the rotor bearing area (for autos), then some on the stem and any other visible and easily accessed areas identified on ETA chart. Then before re-inserting the stem and closing the back, I grease the gaskets.

I've only started doing this in the last month or so, but in some of the watches I've opened up, gaskets had been missing, and non of the auto rotors has ever been oiled (not that I expected them to be).

Sorry, I'm not sure what you mean.

Thanks for the advice!

Thanks for the clarification! I'll check out your stuff

No? This thread is what scared me: http://forum.replica-watch.info/vb/showthread.php/recomendation-for-those-looking-buy-34382

I'll guess I'll take it to someone that can do that, because I sure can't! Thanks for the advice.

"Blowing up" is an exaggerated term, a 7750 won't ''blow up'' on you, if any it will just stop, usually from poor lubrication and dust inside the movement which USED to be the case with the older low-beat 7750's... the new ones are excellent movements [low-beat and high-beat].

What Coldi meant when he said you shouldn't set the date between 10-2 you should be good is just that, don't SET the date between 10am/pm-2am/pm as this is the time the date changing mechanism starts working and you have a very high chance of damaging the mechanism if you do it manually, what most of us do is that we set the time to 6 [am or pm, doesn't matter] and change the date if necessary at that time only to avoid messing up the internals.

I think what Coldi means is that you run into problems when the original 7750 chrono layout is modified to that of other layouts, like those that have a sub-dial at 12. Anything that involves adding some cogs to move a post to a different position.

As for the setting of the date, he is correct, as this also applies to genuine watches. I still have my Tag Heuer "instruction manual" that recommends you only set the date when the time is out of the 10pm to 2am area. This is when the date change mechanism kicks in.

That has been proven to not be problematic with the exception of the seconds at 6 modification, so no worries with the other A7750 configurations.

I knew it was one of those modifications How on earth do they manage to transfer the seconds to the 6 position, and the hours to another? No wonder it has problems

I know there is a mod in which graphite is used, but my understanding is that this will end up doing more harm than good, to the movement.

Not that any of this matters to, as I'm strictly a PAM guy at the moment

Graphite will lubricate the gears/plates so that the friction will be virtually zero, therefore extending the life of the movement. From what I understand it has to be re-done every 6-12 months and will not have a negative impact on the movement.

Would anyone recommend getting a 21j/mineral crystal/auto, or is it worth it to spend another $100 and get the 7750/saphire watch?

Thanks
