Sinclair Brass

The Sinclair Collection by JJ Monaghan is all about timeless style with a modern touch. With a 35mm case that wears perfectly on both male and female wrists, it strikes that rare balance between elegance and everyday wearability. Each piece features a beautifully brushed sunray dial, a classic moonphase display, and day-date subdials—powered by the reliable MIYOTA 6P20 quartz movement.

A sapphire crystal keeps things scratch-free, while 5ATM water resistance means it’s as practical as it is polished. Finished with a soft leather strap, the Sinclair is designed to be your go-to, whether you're dressing up or keeping things effortless.
