Omega Micro Adjust Bracelet PO 2500C/2500D

After searching around the forums I couldn't find a very clear post with regards to exactly what is needed to add the micro adjustment clasp to a 2500 series Planet Ocean.

So here is my experience with it.

Details of watch:
- model number 2209.50.00 (this is the orange bezel but this will work on any stainless steel 42mm 2500 series PO)
- case number 168.1653 (as above)
- movement/caliber 2500C or 2500D
- stock bracelet 1580/952

Parts Required:
- 2 x pins 0128ST0166
- 4 x screws 0124ST3307
- 2 x clasp to bracelet end link 0118ST1589
- 1 x clasp. I went for 0117STZ001154, however 0117STZ001159 and 0117STZ004666 should also work.

You will need a total of 8 x screws and 4 x pins, but if you order the clasp to bracelet end links above from Omega they come with 2 x pins and 4 x screws which is why you don't need to order so many.

Clasp variations:
- 0117STZ001154 - 6 Micro Adjustments (the one I have).
- 0117STZ001159 - 6 Micro Adjustments and a divers extension.
- 0117STZ004666 - 3 Micro Adjustments (slightly shorter - might suit a smaller wrist).

Tools needed:
- 1.8mm jewelers screwdriver. Don't go too cheap with this.
- pin pusher. I have one like this: https://ebay.us/tIVGdp
- loctite 222 threadlocker
- cocktail stick or fine oiler

High level overview of fitting:
- Fit the new end links to the clasp using a tiny drop of loctite on the screws. Put a screw in one side, mate the two together and insert the pin, then insert the screw the other side.
- Use the pin pusher to remove the pins on the clasp of the old bracelet.
- Fit the new clasp assembly to the old bracelet.
If you are uncomfortable with that please just take it to a trusted watchmaker.

The clasp is wider than the original but makes the watch so much more wearable in my opinion. I also don't think it looks out of place. It is nowhere near as good as the Rolex Glidelock, but leagues about the stock clasp.

I also quickly test fitted it to my speedy bracelet that I have never even used and if you use the exact same list as above it will also work (you might have too many screws and pins but that's a minor thing). You will need the end links as the middle part of the clasp is wider on the speedy.

Details of the Speedy:
- model number 311.30.42.30.01.005 (hesalite crystal but sapphire should also work if bracelet is the same).
- case number unknown
- movement/caliber 1861
- stock bracelet STZ004194

If I were to do it again I would go for the one with the divers extension. I may do this again and get that clasp for my PO and use the one I have on the Speedy Pro.

And now some pictures 😀

What parts are needed if you have the 1610/930 "Speedy" bracelet? Will the bracelet end links be the same or something different?

1610/930 conversion is the same like OP's 1580/952, you need;
2 endlinks 0118ST1589,
4 screws 0124ST3307,
2 pins 0128ST0166,
and choose one of the three clasps.

Thanks... can I just call an Omega Boutique and order those? I'm assuming so.

Yes and no. Some will, and some won’t. Just depends on your local boutique.

Well, I don't live anywhere near one... closest one I know of I believe is in VA. I used them to get some pins and tubes for the bracelet a few weeks back. They were kind enough to "give" them to me and ship them two day air via FedEx at not change. Unfortunately, it needed a signature for delivery (seriously, for three pins and three tubes), but I figure that is standard procedure for them, and who am I to complain when they sent them free of charge. Possibly I will give them a call and see if they will work with me. Hopefully the price is not too bad as I know these will not be free.

I've had good luck with a local, major, AD.

I think that the 118STZ000015 is a better endlink for the Speedy, as it is flat. The 0118ST1589 has a slightly curved top, like for the PO links...
