A shape with history
The Cartier Tank, designed in 1917, took its shape from the tanks of World War I and became one of the most copied watch designs ever. In 1931 Jaeger-LeCoultre introduced the Reverso, whose case flips over to protect the crystal, originally for polo players.
Rectangular watches have been a mark of quiet style ever since, worn by artists, actors and anyone who wanted something different from a round watch.
Why they're back
As collectors move toward smaller, more wearable watches with character, rectangular cases are having a moment. Chrono24's 2025 data shows rectangular watches up about 9% in share of demand, and many brands, including microbrands, have added tank-style models.
How to choose and wear one
- Size: rectangular watches wear differently from round ones; measure lug to lug and try it on if you can
- Strap: leather is classic, but a rectangular watch on a bracelet or colorful strap looks modern
- Movement: quartz keeps thin cases light and easy; manual-wind adds tradition
- Style: they pair naturally with a shirt cuff and suit just as well with jeans
