Momentum Aquamatic IV - Blue Dial


The new Aquamatic IV is packed with all the features that make Momentum watches an unbeatable value: a stunning Miyota 9015 automatic movement, anti-reflective sapphire crystal, real Swiss SuperLuminova for great legibility through the night, an offset crown that ensures reliable 200M water-resistance with no “wrist-bite”, and a smooth, 120-click unidirectional bezel.

Reliable Automatic Movement

The deluxe gilt version of the 9015 movement is made in Japan and is one of Miyota’s Premium automatic range, with 42-hour power reserve, 28800 BPH and 24 jewels. This beautiful, slim movement combines form and function, with outstanding reliability, automatic and manual winding, a quick-set date and hacking. Wrap it up in a subtly rounded and shaped steel case with a presentation back and you have the new Aquamatic IV: a refined dive watch that isn’t afraid to be put through its paces.

200m Water-Resistance

Tested to 200m, the Aquamatic IV features a screw-down crown for worry-free aquatic use. The uni-directional bezel is also a useful tool for divers to time decompression stops during ascents at the end of a dive.

What is an Automatic Watch?

An automatic watch harnesses the movement of the wearer's arm to power its mechanism. As the arm moves, a rotor inside the watch rotates, winding the mainspring. This stored energy is then released, driving the gears that keep the watch's hands moving and accurate timekeeping.
