Uncle's notes This is a sleek and sophisticated bracelet that is a great compliment to the greatest Seiko diver ever made. The Senator is a solid link bracelet with solid end-links designed for the SRP Turtles and the vintage 6309-704x model. Heavy and thick, it is a pleasure to wear. It is also compatible to a wide range of wrist sizes (pins for removable links, and up to 6 can be removed). The strap also comes with two, 2.5mm "fat boy" spring bars! What's included One Oyster-style bracelet, one pair of end-links, one pair of 2.5mm spring bars (plus one pair of 1.8mm spring bars with 1.1mm tips as a backup for tolerance issues).
