I've got a 1610/930 coming in a couple weeks and would like to swap to an adjustable clasp. Have you guys stuck to the 20mm clasp or the 18mm clasp...and are you using the same end links as in the receipt?

 

The clasp that I shared is the one You need Mate... it ends with 154 part no. And you are good to go.

 

I used 1589 end links and 1154 (medium size) as well as 4666 (smaller size) clasp with them on my gone 1610/930 bracelet

 

This is what's confusing to me...the 1610/930 tapers to 18mm, so the 154 clasp would be 1mm big on each side. I'm thinking either will work, but one may be a perfect fit versus being a touch large.

 

That's the only way Mate...

 

It will overhang a bit as you said, but would fit / look fine

 

I love this place for all the knowledge...thank you both!

 

Welcome and looking forward to your upgrade Mate...

 

Did you read all 6 pages, I did three watches and the 20mm clasp is no big deal/unnoticeable on the 18mm taper

 

Hello all. First post here. Thanks in advance for any insight anyone can provide. Yes, like most of you I own (too many) watches. Some of these are Omegas. I bought one of the seemingly less popular-sized Seamaster divers for my daughter for graduation. She loves it, and it fits her well so that is what is important. So. The micro-adjustable clasp function of my new (to me) Seamaster 300 titanium is outstanding. I believe she needs the same level of comfort for her mid-size diver ref: 212.30.36.20.01.002 - this is the odd-sized, smaller (but not smallest) one with 36.25 case and 18mm lugs. The band ref: 1516/795, and I believe it has no taper but unsure since she has the watch with her at university...no detailed specs available online either for this watch. An Omega rep did tell me they don't offer the micro-adjustable clasp specifically for this bracelet. I know if there is a viable workaround, I will likely find it here. Wonder Twin WIS powers...activate...form of a clasp solution for my kiddo! Again, any help/advice is appreciated.

 

Hi. You just need to buy the 4666, 1154 or 1159 clasp and it will fit, the end links on her watch does not need to be replaced. The clasp will be a little wider than the one that comes with the watch, but would not look bad. The picture below shows the 1154 clasp installed in my former 212.30.36.20.01.002

 

This is my first post here. Just acquired the same watch (2599.80) and a micro adjusting clasp would be perfect. Did you happen to find out if it fits? Or does anyone else know what else besides the clasp I might need?

Thanks.

 

Hi folks, I've seen this (117STZ001159) for sale on ebay just the clasp without any bracelet links (£159). I assume this will fit straight on to the end links using the existing pins on a 232.90.46.51.03.001 (600M)?

thanks

UPDATE discovered that I need the titanium version which is model number 117tiz004664 as my watch is titanium!

 

Quick nudge here, read all 6 pages and didn't see a part number specific to my reference – what do I need for a 42mm 2500-series Planet Ocean? It has pins, not screws in the bracelet. Noticed one with the expanding clasp on YouTube and have seen photos, but no part numbers in those pages. Do I need the endlinks as well?

 

Already a ton of useful info here. I thought I would add a couple of photos. The camera flash obscured the notches, but they are visible in some of the other photos. These show a little of the adjustable settings:

 

Hi All
New to the forum so please go easy on me !
I hate to open this thread up again and apologies if my question has been answered but being a newbie all the part numbers and nuances here are still a bit of a mystery. I own an old Seamaster Polaris which I love and I recently purchased a Seamaster 300m Co axial chronograph. As others have stated , having an adjustable clasp allows for adjustment during climate change etc and takes the versatility to a higher level.
There seems to be a number of adjustable clasps and I’m a bit confused which one would fit my watch.
I have the following :

Steel on steel
212.30.44.50.03.001
https://www.omegawatches.com/watch-...0m-co-axial-chronograph-44-mm-21230445003001/

The omega store I purchased from states that the adjustable clasp does not fit this watch ?
Any help and advice would be much appreciated.

 

You need to look for posts I have made on this topic, read the whole thread even if I didn't start it. I'm pretty sure if you read as much as I did you will find the answer and have a better understanding. I can't remember everything and have a lot to do today.

 

Yes , thank you.
I re read all 6 pages again just to familiarise and build on knowledge.
From what I can gather I have the updated 300m with the screwed in links. This bracelet is a 20mm taper.

From the info provided here , looks like I can use any 3 options below for the adjustable clasp without the need for additional links to make it fit. It should “bolt” straight on .

I’ll reach out again to the OB today where I purchased from as they didn’t seem to be knowledgeable on this. They insisted that these clasps would not fit ?? I’ll take them to task on this today.

No divers extension , just the Micro adjustments.
Micro adjustable: 117STZ001154 for 20mm or 18mm.

Micro adjustable With divers extension: 117STZ001159 for 20mm or 18mm.

117STZ003191: for 20mm or 18mm "007" micro adjustable clasp:

 

Forgot to mention - there is also the smaller adjustable clasp that has only 3 adjustments
117STZ004666
This seems to be very similar size to the original clasp - it has the adjustment and no Divers extension - should fit 20mm band with screw in link and no further parts needed to fit ?

Ive made the call into my OB and they are checking again.............. Hopefully they will come through with at least one of the options.

 

So, just to be sure: the 154 has no 007 logo and will fit my 212.30.41.20.01.003?

If so I’m ordering one at my AD tomorrow.
