I finally got the buckle for the X-33 Coramid Kevlar strap. It came much earlier, not the 2 months promised by Omega. Talk about managing expectations. Anyway, on to the buckle. The buckle I ordered is not really for the strap. Omega (Taiwan) was not able to help furnish me with the correct buckle for the strap. So the buckle ordered is based on the recommendation on the Ofrei site. Additionally I have checked pictures of other X-33 with the Coramid Kevlar strap and the buckle looks to be similar to the ones fitted to the strap.
The buckle, fresh and new from Omega.
The parts that makes up the buckle.
The buckle, part number 9451-1803, is made of stainless steel. It has a satin finish. Why not a titanium buckle? Well, I understand that Omega does not make titanium pin buckle. So this buckle is the best option for the strap.
As you can see in the pictures, I have installed the tang the wrong way round.
This mistake corrected.
