San Martin SN0148 37.5mm Automatic Mens Diver Watch, Miyota 9015, Sapphire Crystal, 200m WR – W/Code – Sold by San Martin Official Store

The San Martin SN0148 is a compact automatic dive watch for anyone who prefers something a little more restrained on the wrist. This version measures just 37.5mm across and around 11.35mm thick, while still offering the specifications youd expect from a substantially sized diver, including 200m water resistance, sapphire crystal and a screw-down crown.
Inside is the well-established Japanese Miyota 9015 automatic movement, while the enamel-style sunburst dial is available in several colours, including Black, Blue, Green and a Limited Red option.

The Miyota 9015 is a particularly nice choice for a watch this slim. Its a relatively thin automatic movement with hacking and hand-winding, helping San Martin keep the SN0148s case thickness down without resorting to a quartz movement.
Dial options
Theres a good selection if Black isnt your thing, with Blue, Green and Limited Red versions also listed. The sunburst finish should give the dial noticeably different tones depending on the angle and lighting.
Just check whether all colours are the same price before ordering, particularly the limited version.
