Blue Bezel Edition — 1 of Only 2 Pieces Made Worldwide
In 1730, John Harrison changed the course of maritime history with the invention of the marine chronometer. The Marine MKII 1748 Chronometer Calibre is Bowman London’s tribute to that legacy — a contemporary field chronograph honouring Britain’s role in advancing global navigation.
This special edition — one of only two pieces ever produced with a blue bezel — is crafted entirely from 316L military-grade stainless steel, featuring a sunburst light grey dial, luminous hands and markers, and sub-dials at 3 and 9 o’clock for 24-hour and 60-minute readings.
Its profile is bold but refined, with a screw-down crown, pushers, and case back, delivering 200 metres of water resistance. Protected by sapphire crystal and powered by the Japan VK64 Mechanical-Hybrid movement, this is a serious watch — made for those who appreciate both history and purpose.
