In Context

At 38 mm it sits just under the modern norm — the band that suits the widest spread of wrists. The 6.82 mm case is genuinely slim and goes under a shirt cuff without argument. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse.
