The mighty Oceanographic 4000 (beginners review)

[santre22]

Big thank you for such detailed info!

Just a question refering to your #4: when doing replacement of center seconds wheel from Asian to ETA version - I will have to grind a tip of ETA pin, I suppose. That mentioned 0.05mm, right?

Yes the Asian center sec is 0.20mm and ETA is 0.25mm, it was very difficult to hold the wheel when grinding it so i destroyed 1 wheel first... so it was another 22 usd for a new one.

About the weight the gen is quite heavy too actually I hold it and study it very close at the AD, the caseback is super thick (2 mm titan weight more than 1 mm SS for example). The crystal is super thick 6,5 mm the 7750 movement is quite big compared to 2824, 2892 etc. so the weight i say is the same. All parts in the case is titanium only steel i find is in the screws. thats make a different in less than 1 gram between titanium and steelscrews.

Thanks for the tips with the lens cleaner i will try it so i hope i get the watch readdy soon

Now my V6 housing a swiss ETA 7750 serviced an regulated and it running super well!!
(+001 s/day 0.1 ms 298deg) Dail down
(+002 s/day 0.0 ms 300 deg) Dail up
(+000 s/day 0.2 ms 277 deg) Crown up
(-001 s/day 0.0 ms 280 deg) Crown left
(+002 s/day 0.0 ms 279 deg) Crown right
(-003 s/day 0.1 ms 275 deg) Crown down

Also the case is cleaned and waterproofed to 10 atm again to be sure.

Case disassebled look at crystal thickness thats awsome!

New ETA movement disassembly before cleaning:

I will now check for the powerreserve and aiming on atleast 40 hours (42 h)

Wow! What a look inside a sure to be "Super Rep". Congratulations on taking on this mod and succeeding. I would love to see more pix of the disassembled case etc if you have any.

Great photos. Thank You!

 

[santre22]

I am sorry about the photos this is the only i take i was to urgent to get the watch together again. But there will for sure be more photos in the futures of modding other watches.

Another tip is the axis to the crownguard it have 2 rubber gaskets to make a smooth open/close. Lube them with little silicone grease and the open and close will feel exactly on the spot and they last longer! (Mine was dry from factory)

Santre22, do you have any idea how to make internal bezel operations more smooth? Mine gets stuck at the same place all the time: goes smooth almost whole turn and stops at the lat 5 minut where you can turn the 2 o'clock crown recognizing only one teeth per turn catches the bezel... about 20 turns to just move the bezel on 5 minut distances... maybe one can make the bezel crown gear bigger or something..?

This action is definitely not normal. My bezel moves silky smooth the entire 360 degrees without any added action to move at any point in the rotation.

Mine is also turning smooth as silk.
The only i can think of is that your bezel teeth is damaged in that area (bezel construction is bezel in painted metal and glued to a bottom bezel with gears in plastic.) The gear on crown axis is in steel so it will damage the plastic gears if its not correct mounted so my advise is to not turn the bezel more before looking the problem up.

But i have sometimes problems to align the bezel marking \/ over the 12 index. it changes little when screwing down the crown. But i think thats my techniques fault cause i had same problem with the genuine..

That's why I think it is not exactly the problem with damaged bezel teeth - but more with the length of the crown pin - it is too long since it is enough for me to barely press crown in and all is disengaged. It is impossible for me to move the bezel while screwing down the crown. I will check it this weekend.

The gear and bezel theeth is always engaged. the axis is a two part spring loaded construction that disengage when push in the crown, it also if you turn the bezel clockwise slip on some kind of spring loaded gear if lubed correctly.


About my power reserve on with the serviced ETA7750: 43 h 45 min still running
(The gen have 42 h power reserve in specs)

Still running or still running accurately? There's a difference.

It have been dail up on the table and it now +4 sec over the soon 45h. I will say thats quite good. (still running! )

 

[PolonusTM]

Mine is +1s after two weeks (!). It is so good I am a bit afraid the servicing as planned for this weekend might make it worse. I hope it will not happen like that. The watchsmith will try to repair the bezel thing. I will let you know by Monday.

 

[santre22]

And now it have stopped.

Power reserve is 48h and 20min way better than i hoped! In the bitter end i think the watch got slower cause it got from +4 to -1 sec total when it have been running for about 47h.

 

[PolonusTM]

Well, I got my diver from servicing. I was also visiting watchsmith several times during the process. Conclusions:

- replacing "chronograph wheel friction" part for ETA gen counterpart didn't matter to smooth seconds hand movement
- regulation of pinion/seconds wheel engagement - that works! Now seconds hand moves much more smooth - on par with gen ETA's as we checked by eye. It is not perfect smooth anyway, especially with this BIG Hublot seconds hand
- plastic gears on the other side of the bezel are cheap, of bad quality I was not lucky - some part of these gears were apparently not molded good enough - they are not 'grown' high enough :/ Anyway, I set the bezel in my favourite position (20 at the top) and will not mess with it.

10 atm test passed with no problems.

 

[smascarinas]

This is my movement... At least it's an ETA too bad no decorated Rotor, but no 7750 wobble.

But with this movement you dont get the choppy sec problem and also who will ever look inside your watch.

Also on the pic of the dail on your watch is it lume on bezel on your version?
My all black carbon diver 4000s bezel does not have any lume at all.

 

[smascarinas]

Mines a No lume version.
