Which movement are we talking about? You probably messed up the keyless works. The only solution is to remove the dial and hands and put the parts that moved back in place... PS: Better ask mods to place this thread in the 'repair & upgrade' section. You will get more answers there.

Mine tested to 5ATM which equals to aprox. 50 meters. So some leisure diving wouldn't be a problem. If the mod was done in the same way I don't see a reason why it should fail You could have yours tested or just take the chance after you've done the mod.

You will have problems with the hands, stem and movement spacer for starters... Good luck on the project.

Damn, all those versions are even driving me crazy It's a V1 case (see the curve of the lugs), V1 dial (missing tick), V1 case back (logo not embossed enough) ,V1 bracelet (curved end link cut outs), V1 rider tabs (nice and deep), V1 clasp and fold (French engravement), V1 chrono pusher ( beveled sleeves)... it probably has the etched 'b' on the side of the bezel. Just like the V1 And indeed new date wheel (as all a7750 Breits that are comming out have), AR and silver hands. So it's definitely a V1 with some updates

Great job! This watch will give you more pleasure than any gen. That does feel good doesn

V2 case, V2 dial, V2 case back, V2 bracelet, V2 rider tabs, V2 clasp and fold, V2 chrono pusher sleeves... do I need to go on? This is a V2 with the only exception it has AR and silver hands.

Don't want to spoil anyone's party but this is V2 with updated date wheel. Nothing more nothing less.....

Well, getting the inside of the crystal spotless is THE hardest part of it all. I know members who almost lost their minds trying to get the dial and crystal dust and spot free I use a fiber optic cloth which you can get with every optician (mostly they give it for free when you ask nice). I tried different fiber optic cloths but most of them still seem to give off very tiny particals. The fiber cloths which are used for reading glasses have the finest structure which gives the best result. First I use my breath to fog up the crystal from the inside and then I rub it nice and clean with the fiber optic coth. I check for dust and particals under a heavy spot light and on a black background (this way the mostly white dust specs can be seen best) before I decide to put the movement back in. It's trial and error. Good luck!

Thanks for the feed-back. Glad my tutorial was of help

Man, you almost had me there Give it a year or so. First there will be the cheap Canal version... after a while the high-end version.

Shoot me a PM. I have a spare

A toothpick shaved flat on 1 side (like a spatula)

I can't understand why nobody paid him a visit...... Either to ask what is going on or to kick his ass! If this guy lived in The Netherlands I would bring a f*cking army to his doorstep!

Welcome MagnusW! Take a look in the dealer section. All the info on prices and contact can be found there.

How tight it screws down has nothing to do wether it's water proof or not. It depends on two main factors. 1 Design: The crown and HEV must have the right dimensions. For example: if the tube is to short the crown won't screw down far enough and therefor the tube won't touch the rubber seal inside the crown. 2 Seal: If there is no rubber seal but only metal on metal water will enter. It's therefore important the metal contact points of the cown and HEV are joined by a rubber. This applies for all moist; rain, washing hands etc.

Couldn't have said it better!

The major problem with the A7750 although brand new, it usually is assembled in a dirty environment. So new but dirty movements are very common in our reps. If your jeweler can't fix it himself he will probably know a watchmaker who can, just ask

Dear Freddy, please elaborate. Does one not need a vibrograph for a correct beat adjustment? How do you go about?

This is not causing the low PR.

Than it has to be something jamming the chrono module. It has to be taken apart to see what is causing it. For a skilled watchmaker this shouldn't be a problem. The movement is probably dirty or a gear could have lost some theeth?

Try a local (non-branded) jeweler shop :One that does NOT carry high-end brands like Rolex, Omega, Breitling etc. They usually have no problems working on reps.

Indeed. You're on the right track

You're missing a lot! Hands Stem Crown Tube Right movement spacer (impossible to get so you probably have to make it yourself) And in the end you will still have a majorly flawed PO..... You should better do some more reading and learning before starting such a project

Yes, now it's truly functional Nice wallpaper:

It's just a simple slipping second hand. It's a $10 fix. Bring it to a watchmaker. You only need to remove the movement, remove the hand, glue the post and put everything back together.... The chronograph works fine. Just the hand that is slipping
