I got a used PO 232.30.42.21.01.001the other day. Got it for a song (comparatively) and it's in great nick, except that the clasp has been polished and re-scratched and it's just bugging me. It's also either very snug with the half-link out, or a bit loose with it still in.



So I thought I'd look into getting the "push" clasp for it. After a bit of looking around here and on WUS, I believe the part number I want is the 117STZ001154. I initially thought it was 18mm (same as the current one) but apparently it's 20mm. There seemed to be some confusion on various threads about this, as apparently there is an 18mm (117STZ000824) which at least one person has gone ahead and bought only to find out it's the butterfly AT style. So as far as I can tell the 1154 is the only adjustable clasp that is suitable for the 42 and 45mm POs and SMPc. It doesn't sit flush with the 18mm bracelet, but I think it's OK. What do others think? Has anyone done this on their 42? (pics from another site)





So apart from the aesthetics, am I right in thinking that it's a straight swap on the 1589/858 bracelet? It doesn't need any other end links?




And finally, there's the usual issue with Omega getting funny about providing a part that wasn't original to the watch in question. I emailed my AD regarding ordering one and slightly mis-quoted the part number (I put a "0" at the start, but you'd think that they'd have figured out the mistake..). This is what I got back.

I contacted Omega materials as the part reference you supplied was not showing on their order system.

I had advised you wanted the mirco-adjustment clasp however the advisor explained the clasp will not fit onto an original bracelet, it is made for the new style Planet Oceans only. I did enquire about a complete bracelet price for you to consider however Omega advised the new bracelets do not fit onto the old style case.

Sorry I couldn’t be of more help on this occasion.

Rather typical. I'd appreciate any concrete intel from anyone who has swapped out this clasp for the adjustable one, and if they can confirm the part number is correct and that it will, indeed, fit OK without any further modification. Or should I just get the bracelet and clasp valeted back to proper brushed and put up with the snug fit (which isn't too bad, but might get a bit uncomfortable on a "fat wrist day"?). Cheers guys!

 

Really? Has no-one done this? I realise that maybe my issue isn't a big deal with all the ST / 60th excitement , but surely at least one gem of knowledge is out there..

 

My OB offered to swap my 3313 to the adjustable clasp...

 

Forgive my ignorance, but 3313?

 

You need to put 2 half-links and take out 1 full link to make the perfect fit (the half-link is a misnomer as it's not exactly "half" when measured. It's slightly bigger than a half). This is the most elegant solution.

As for the adjustable clasp, I believe the part number is 0117STZ001154 (SS) or 0117TIZ001151 (Titanium). You also need to buy the 2 endlinks O118ST1589, 2 pins O128ST0166 and 4 screws O124ST3307. The bigger clasp may not be perfect but it's the only thing that works on the PO 8500 42mm as far as I know. Don't take my word for it though as I've simply read this info on the forums.

 

It is a strait swap. I also have a 42mm 8500 PO. I picked up mine from and Omega boutique on the recommendation of the sales associate. He installed it there at the boutique and no end links were required. I don't have the part number with me but I will try to look it up later.

 

3313 is the movement number for the orange PO in Foo2rama's profile picture.

 

Here is a pic of the clasp part number from my receipt. Part number 0117STZ004666. This clasp gives you 4mm of extension. The 1154 clasp is quite a bit longer and gives you the ability to extend the bracelet quite a bit. I’m unsure if new enlinks/screws need to be purchased to use the 1154 clasp. I was under the impression that end links only needed to be purchased when retrofitting to a bracelet with tube & pins (I could be wrong though).

 

That's interesting. But my wrist size does tend to fluctuate. Only slightly, and not an issue generally, but, with the PO being heavier than most, any kind of slack and I can feel it moving around. That's why I want the adjustable chappie..

And therein lies the problem...

 

Ah. The plot thickens. So are you saying that the 1154 and the 4666 (which is new to me) will both work, but the latter is just shorter with less "travel"? Is the 4666 also 20mm? Hard to tell from the pic, but it looks like it is slightly wider than the bracelet, like the 1154 is. Not a big deal. Thanks very much for that matey...

 

@nurseford25 Would you be able to tell me what the length is of that? It looks significantly shorter than the 1154. Presumably it also has more limited "adjustability" as well..

 

Yes the 4666 is 20mm as well. It gives 4mm of extension. I'm not sure of the exact difference in length between the 4666 and the 1154 clasps. I will say that the 4666 is just about the same length as the clasp that came on my PO, maybe 2mm shorter but definitely pretty similar in size.

 

Thanks a lot for your input. I had no idea that the 4666 existed. Sounds like the better option..

 

I didn't know either till I was at the boutique. Who knew? Hope it works out. I love mine.

 

Thanks mate. Your help has been invaluable and much appreciated.

 

Please let me know how the 4666 turns out, Mozziebite. Might as well buy one for my PO and join you gentlemen.

 

4666 is definitely the better option then. I have the 1154 and I ended up have to take out one half link to make it fit right on the wrist.

 

Plus the 4666 is only $61. Can’t beat that.

 

. As Agent Mulder would say, The Truth Is Out There...

 

Wow, that's ultra reasonable. Thanks for sharing.
