Cartier's tiniest watch, the Mini Tank Louis Cartier, has graced the wrists of many a celebrity over the past year. Think Paul Mescal, Timothée Chalamet, Rami Malek, and the like. If Cartier has been the Maison leading the small watch movement, then the Mini Tank LC is the ultimate expression of that craze.

Yet, for a watch so tiny, it packs quite a punch on the wallet. More specifically, one that will set you back a minimum of ten thousand pounds.

Citizen, however, has something to say about that. Earlier this year, they released a range of Fio Roma watches that do an excellent job of reproducing the same daintiness and dressy elegance of the revered evening watch.

Measuring just 17.3 by 24.5mm, the Fio Roma is a line originally intended and marketed towards women. But the truth is that watches have no gender, and it is precisely this androgyny that sparked the small watch boom in the first place.

From the silver sunray dial adorned with Roman numerals to the crown set with a black cabochon gemstone at three o'clock, and from the rectangular gold-toned steel case to the embossed leather strap, one would never expect a watch this refined to house a solar calibre. As Citizen's smallest Eco-Drive movement, the Calibre G620 runs on energy generated from light of any kind.

This, of course, means you will never have to worry about swapping batteries. Citizen has a proven track record of delivering around 20 to 40 years of reliable timekeeping without requiring a battery change.

The trio of releases comes in three colour schemes: a silver-coloured case with a black leather strap, a yellow gold-coloured case with a dark brown strap, and a rose gold-coloured case with a dark grey strap.
