SEIKOgenuine Divers urethane rubber Watch Band DB73BP 20mm

Fit correctly.

Ok

Perfect fit.

OEM. SOLID and original. Perfect.

This band looks fine, and works ok. It’s probably going to last quite some time. However, the rigidity has a negative impact on the level of comfort. Take a regular Casio G-Shock band for example; the angle that the band makes with the back of the watch is wide (120 - 130 degrees or so) and is very accommodating. This is how a thick, resin band can be made to be comfortable. But with this band, the rigidity will simply not allow for such angles to happen smoothly. So it wants to make a 90 degree angle down from the back of the watch to the clasp/buckle, and because the curvature of the wrist is in the way, it forces the band to bow out, thus pushing on the sides of the wrist, thus causing discomfort.

It’s great

This is great replacement for a canvas strap on a Seiko 5 series watch. It brings the watch closer to a sporty diver watch and adds some heft to it - that's hard to explain until you see it on your wrist. The rubber strap is flexible and contours to your wrist on the first wearing. Replacement does require special tools or a trip to a jeweler as the strap pins are very small, with the right tools it can be done in minutes. The Seiko 5 is an amazing value for an automatic watch - I fondly refer to mine as a "Baby Grand Seiko"

The band is made by Seiko but a perfect fit for my Citizen Ecodrive Diver’s 300M watch. Comfortable. Easy to put on and take off. Great Seiko quality.
