From left to right, the original TT Geophysic pin buckle, a deployant buckle similar to the one that comes with the Geophysic True Second, and then the more regular deployant buckle we've all seen before.
I got the pin buckle with my TT Geo and the classic deployant courtesy of my AD. The newer style, I had to order it through the Vendome boutique and wait for 5 weeks to actually get it. Patience!
I really like the deployant ones, vert comfortable, easy on & easy off.
What about yours?!
