## Description

Seiko Men's quartz titanium watch with textile strap SSB421P1

Review: Great Watch - Really good watch, especially for the money. Typical Seiko, superb quality and one of the best at the price point.
Review: Stunning watch!! - The level of detail and precision on this watch is incredible! Nice weight to it and not too big or chunky. The strap is a little firm at first until worn in but to be expected. My only gripe was with the delivery. Took a few days with desertcart for a purchase of £270 which is unusual. Highly recommend this watch to anyone contemplating buying one however.

## Features

- Robust casing: a titanium carbide coating gives the case its dark colour.
- Flexible textile strap: the high-quality textile bracelet ensures maximum comfort on the wrist. Thanks to the classic pin buckle, the strap length can be easily adjusted to the individual wrist circumference.
- Scratch-resistant sapphire glass: the valuable, man-made sapphire crystal has an enormous hardness that is only surpassed by the diamond. Sapphire glass is therefore less impact sensitive than mineral glass and extremely scratch-resistant.
- Waterproof wristwatch: the watch is waterproof up to 10 bar, i.e. at a depth of up to 100 metres. It can therefore easily withstand accidental water splashes when washing hands, rain or sweat.
- Diameter 39.5 x 11.6 mm
