    Hi All - sorry if this has been covered. I’ve searched extensively and can’t seem to find part number information regarding half links for a 42mm PO 8500 Titanium. The bracelet is 1589/ 858 titanium and is 20mm tapering to 18mm. If Ti is too difficult to find stainless seem available, however, is there a risk of galvanic corrosion? Thank you!

    In theory, the reference should be: 115ti1589, since the SS version is 115st1589. But I couldn’t confirm that on cousins so you may need to check with your AD.

    I don’t know about corrosion, but the colour difference between the SS and TI links will be enough that you won’t like the look. Maybe consider the adjustable clasp mod as an alternative?

    That is correct for a half-link, and an Omega OB or AD can sell them he calls them.

    Sometimes I found that in cases where adding a half-link is too much, that removing a full-link and adding two half-links could be perfect. I think that a half link is more like 60% of a link, not 50%, so 2 half-links could be like 1.2 to 1.3x the size of a full link (it could be more like 65%, I'm not sure).

    I always prefer an adjustable clasp, and used a 117TIZ001151 adjustable clasp, which for a 42mm watch I think that needs two 118TI1589 clasp links (plus extra pins and screws) to adapt the 1151 clasp to the smaller bracelet that tapers from 20mm lugs to 18mm at the clasp (I think the 1151 is a direct bolt on for a 45.5mm Planet Ocean with 22mm lugs tapering to 20mm).

    However, places like www.SwissWatchSpares.com want £99 for a Ti half-link or a Ti clasp link, and £449 for the Ti clasp. So 2 half-links is significantly cheaper than a clasp + two clasp links + extra screws and pins. I'm pretty sure my OB charged me half those costs to sell me the parts I needed in 2015/2016 for my old 42mm Ti 8500, before many OB's stopped selling the parts.

    I also purchased the adjustable clasp for both my Diver 300 and my PO 8500 Ti. Please call an OB first as it was considerably cheaper than randomly sourcing parts. I seem to remember that the titanium adjustable clasp was twice the cost of the stainless steel but I wanted the matching clasp.

    Called local AD and you are correct on the Ti Part Number. $99 for the Titanium half link. Gonna try 2 half links because I like the 18mm Ti Clasp, and it’s cheaper!

    Great. The beauty of the half links being about 60-65% the length of a full link is that IF a half link makes things too big, then replacing a full link with two half links will only be 30% bigger than the full link. You get 4 sizes with 2 half links and 1 full link > smallest size is replacing a full with a half link, then next up is using full link, then next up is using 2 half links without the full link, and largest is a full link + half link (or two).
