Swatch's new SISTEM 51 models


We're no doctors, but there's a risk you're about to feel a sudden, uncontrollable pang of envy in your wrist. 

Ahead of the fashion-fuelled fiesta that is London Collections Men, Swatch has unveiled two new models of its SISTEM51 - a 51-piece (hence the name) automatic timepiece, held together by a single screw. 

The elegant canvas of the Swiss-made piece - which holds an impressive 90-hour power reserve - has been reworked in two new models: the military-themed SISTEM NAVY (above) and the contrastingly clean SISTEM INCOGNITO (below).

You'll be able to pick up one of these self-powered beauties for £108 from Swatch's flagship store at 313 Oxford Street, London, from 12 June.
