I purchased this watch on the titanium bracelet and ordered both the rubber and alligator straps as well as the 2 links that must be changed in order to accommodate straps, and the deployment buckle.
The links are attached to the watch using 2 small screws on both sides of each link. I’ve attached some pics. Excuse my poor photography.
Hope this helps anyone thinking of buying this watch and changing straps. If you’d like to know what I paid and where I bought everything, send me a private message.
