OMEGA Seamaster Aqua Terra 150M

Omega's Seamaster Aqua Terra 150M, reference 220.12.41.21.03.007, has a steel case measuring 41 mm across. Thickness runs to 13.2 mm with a lug-to-lug of 47.9 mm, and the blue dial sits under a domed sapphire crystal with anti-reflective treatment on both sides. The self-winding calibre 8900 drives the watch, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss, with two barrels and a power reserve of 60 hours. A date function and a time zone display are built in, and the screw-down crown adds practical security. A sapphire caseback shows off the rhodium-plated rotor and Geneva waves finishing. The blue rubber strap closes with a steel folding clasp. Water resistance reaches 150 metres.
