Editor's Notes

From the 'Armed Forces' collection, Bremont's 'Argonaut' diving watch is crafted from bronze – the metal has long been used in the naval services for its hardiness in salt water, and this CuSn8 alloy is especially corrosion resistant. Powered by a COSC-certified movement, it offers military-grade precision for up to 300 metres deep – more than meeting the demanding specs of the original 'Dirty Dozen' watches commissioned in the '40s, as well as the Force's standards today. It's finished with a Sailcloth strap.
