UncleSenator Bracelet (Seiko SPB31x Slim Turtle)
Uncle's notes:
The Slim Turtle 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 Senator. A favorite among watch enthusiasts of all levels, the Senator is a simple but versatile bracelet that looks great on any occasion.

Will this fit my watch?
This strap is specifically designed for a specific watch model.
Please check the description to see if your model is there. If your watch is not listed there, chances are it won't fit.
Each watch is different and the curvature of the case as well as spring bar hole positioning is different so it's impossible for us to know if this will fit your watch without testing it.
