Some watches are bought for an occasion; the Tissot PR 100 Lady is bought to be worn every single day. Reference T101.210.11.031.00 is the purest version of that idea: a 33mm steel case, a silver dial and a matching bracelet, with nothing extra to distract from good proportions and Swiss reliability.

The PR in PR 100 stands for Precise and Robust, a name Tissot has used for its everyday sports-elegant watches for decades. That promise shows in the details. Sapphire crystal resists the scratches that come with daily wear, the case is water-resistant to 100 meters, and the ETA F04.111 quartz movement includes an end-of-life indicator that warns you before the battery runs out. Luminous hands make the time readable in low light.

At just 9mm thick, the watch slips under a sleeve with ease, and the polished and brushed bracelet closes with a push-button folding clasp. It pairs as naturally with a blazer as it does with jeans and sneakers.
