Micro Adjustable Clasp Help

So I have a 42mm PO 2201.50 I am looking for the correct adjustable 3 or 6 position clasp for it. I have been doing some research and found that the 117STZ001154 (this is the 6 position) works on the new PO's I am unsure if it will work on mine (the newer PO's have the screw pins. Mine have the push pins). Would I need any additional links?

You need to make sure you have the correct attachment links. You can mix and match screwed links and pin links, that works ok. You might consider getting the 117STZ001159 clasp instead as it has the wetsuit extension.

Thanks. I do not need the wetsuit extension. So I was going to get the model without it.

No reason you can't. 😀 My hands are too big for my wrists or perhaps that's the other way around so sometimes I need to pop it to get the watch on.

Not sure which bracelet you have but here is the advice on https://www.swisswatchspares.com/ website regarding fitment

BRAND NEW GENUINE OMEGA STEEL ADJUSTABLE CLASP
117STZ001154

THIS CLASP CAN BE SWOPPED WITH YOUR NONE ADJUSTABLE MODERN SCREW AND PIN DESIGN BRACELET CLASP LIKE THE 1515-816 / 1616-749 / 1589-858 / 1590-867 / 1591-831 CLASP IF YOU PREFER THIS ADJUSTABLE VERSION.

IF YOU WANT TO ADAPT YOUR LATEST SPEEDMASTER MOON WATCH 1958-957 BRACELET TO A MICRO ADJUSTABLE CLASP THEN YOU WILL NEED 2 OF THE 118ST1589 CLASP LINK AND THIS CLASP, PLEASE NOTE THE CLASP IS SLIGHTLY WIDER AT 20MM BUT OMEGA DO NOT MAKE AN 18MM VERSION AT PRESENT.

IT CAN ALSO BE FITTED TO AN OLDER STYLE BRACELET IF YOU PREFER THE MICRO ADJUSTABLE 20MM CLASP, HOWEVER YOU WILL NEED TO PURCHASE 2 OF THE LATEST CLASP LINKS PLUS EXTRA SCREWS AND PINS IF YOU WANT TO ADAPT AN OLDER FRICTION PIN DESIGN BRACELET.

Basically to adapt the old design 1610-930 / 1612-932 / 1580-952 / 1998-849 bracelets which have 18mm clasp to accept this latest slightly wider 20mm micro adjustable clasp you need 2x118st1589 clasp links, if you have the 1503-825 / 1504-826 bracelets then you need 2x118st1515, the 1579-951 / 1581-953 Planet Ocean you need 2x118st1590.

The micro adjustable steel clasp currently available from Omega are 117stz001154 117stz1159 & 117stz004666 shorter version (unless you buy the limited edition 007 SPECTRE clasp) and they don't include the screws and pins. You will therefore need to purchase an extra 4x3307 screws + 2x0166 pins along with 2x latest clasp links to fit this micro adjustable clasp to the old design bracelets.

When my watchmaker fitted the new clasp links to the 1610, he chose to drive the new pins through the tube in the bracelet's center link. It's a tighter fit that way though if you were going to take it off (no reason to, really) it would need to be driven out with a punch and hammer.

Thanks for the help. Went by the Omega Boutique and the Watchmaker took care of it for me. Like you said new clasp and 2 new end links were needed. The good new is that I am going to get a Speedmaster and the clasp with work, but I will just need two new end links.

Hello all:

I have this exact same PO - 2201.50.00 - which I love wearing but would like to add the adjustable clasp. By looking at this site I have determined that I need the following parts:

Clasp 117STZ00154 (6mm - no diver's extension)
Link 118ST1589 X2
Pin 128STO166 X2
Screws 124ST3307 X4

I have a lead via the dealer that I bought the watch from who has a watchmaker in his building that can order parts from Omega HOWEVER, apparently he needs the reference numbers for the watches that these parts come FROM in order to input the information into his ordering system. Could anyone help me out with that?

Cheers, Steve
