Seiko Prospex Alpinist SPB117

The Seiko Prospex Alpinist SPB117 combines a black dial with a 39.5mm stainless-steel case and matching bracelet. It is an outdoors-inspired automatic watch with enough restraint to wear beyond the trail.

Why this watch stands out

Seiko’s 6R35 automatic movement offers approximately 70 hours of power reserve. The case measures 13.2mm thick, with a sapphire crystal featuring an anti-reflective coating on the inner surface. Water resistance is rated to 20 bar (200 meters).

What to know before you buy

The SPB117 is the black-dial, 39.5mm Alpinist on a steel bracelet. If you want an automatic everyday watch with a substantial water-resistance rating and a more understated dial, this configuration deserves a look. Because it is mechanical, it may need winding and resetting after sitting unworn longer than its power reserve.

Our take

The black dial and steel bracelet make this Alpinist a versatile choice for someone who likes the collection’s outdoor heritage without committing to a bright color or a leather strap.
