Who should buy which.

The PR 100 Green: Someone who wants a slim Swiss everyday watch with a colourful dial. Choose the black PR 100 if you want the most neutral version, or the green chronograph if you want a stopwatch.

The PRX 40mm Quartz Light Green: A buyer who wants the PRX silhouette as an easy everyday watch, or a first good watch that does not need winding. Choose the Powermatic 80 version if a mechanical movement is part of the appeal, or a lug-and-strap watch if you like to change the look often.

Before you order.

Like the other PR 100 models it is a simple quartz three-hander with a date, so it adds colour, not complications. Tissot does not publish a lug-to-lug figure; the case is 40 mm in length and width.

There is no exhibition caseback or mechanical movement to enjoy, and the integrated bracelet limits strap changes to PRX-compatible options.
