Uncle's notes:

The Slim Senator is a great watch for many reasons - comfortable size, clean layout and bold, lumed baton indices that provide excellent legibility.  At its core, the SPB31x is a classic Seiko dive watch, though with a more modern, sleek case that only adds to the wearability.  

Seiko divers are known for their durability and timeless aesthetic, and the Slim Turtle is no exception.  If there's one bracelet that checks both boxes perfectly, it's the humble Oyster.  A favorite among watch enthusiasts of all levels, the Oyster is a simple but versatile bracelet that looks great on any occasion.

This Oyster features the flip-lock divers clasp and 6 removable screw-type links.

One bracelet, one pair of end-links, one pair of 2.5mm spring bars.

      Wondering if this product will work with your watch? I do my best to outline compatibility details here so you can ensure a good match.

      For bracelets, some of the compatible models listed are submitted from my customers, and therefore I can't guarantee the fit will be perfect.

      Occasionally these matches require some light modifications to fit correctly. I've outlined these steps over on the Bracelet Mods, Tips & Tricks page.
