The Hamilton Intra-Matic Auto Chrono is a modern reworking of a 1968 signature piece that offers a sporty but classic look. Combining authentic 60s appeal with the exclusive H-31 automatic movement, its distinctive panda dial is a guaranteed eye-catcher. This Hamilton leather strap is made from natural materials. The leather is tanned, but has not been treated, pigmented and finished in the same way as some other leather straps. This helps it to retain its natural look and also means that every piece is not exactly the same. As a result, the color of the leather strap may differ from the color shown on the image.
