For sale is a used STZ001159 Omega clasp featuring 6 micro adjustments and the divers extension. Clasp functions well, adjusting smoothly and closing tightly inc the divers extension. This is a popular mod part to convert other bracelets to micro adjustable. This comes w/20mm "Bond style" connecting links so will go right onto some bracelets, for 18mm you will need to buy the correct connecting links (eBay, OB, AD, OF). Cosmetically in good used shape with some light scratches and desk diving marks. Please check out the pictures and feel free to PM me and ask for more if you have questions. I dont take returns unless I make a mistake in the listing, in which case I will always make it right. I bought this to do the conversion on the bracelet for my 2531.80 but I always wear it on the rubber strap so it just sits here; time to move it to someone who will use it. $220 (was $265) OBRO paid by Paypal, F&F always preferred but G&S is no issue and I wont charge you an extra 3-5% just $265 either way. That includes shipping in the USA. US sales preferred but I will ship overseas as well, shipping will be extra and it will need to be $265 USD net to me as paypal international transaction fees are much higher. More info on adding to other bracelets can be found here: https://omegaforums.net/threads/micro-adjusting-clasp.37817/ and in many other threads as well. 20yrs of positive eBay transactions (dperie) and one bit of feedback here as well: https://omegaforums.net/threads/140dave-is-a-great-seller.122831/ Pictures! Questions? PM/DM me please. As always, thank you OF for the space!
