Our take on the SPB379 Prospex Alpinist GMT 39.5mm

The SPB379 is a 39.5mm Prospex Alpinist with a GMT hand, a rotating inner compass bezel and a stainless steel case on a matching bracelet. It follows Seiko's 1959 Laurel Alpinist in style while adding a traveler's second time zone, which puts it between the simpler three-hand Alpinist models and the larger, pricier Prospex GMT divers. Owners rate it highly for its compact case, legible dial and the value of a mechanical GMT with 200m water resistance at this level.

About the SPB379 Prospex Alpinist GMT 39.5mm

Inspired by Seiko’s first sports watch, the 1959 Alpinist.

Questions and answers

Is the SPB379 a true GMT?
Yes. The 6R54 movement has an independent 24-hour hand, so you can track a second time zone while the main hands show local time.
How does it compare with the standard Alpinist?
It adds a GMT hand and a 24-hour chapter ring, and it is thicker than the three-hand Alpinist models. The case stays compact at 39.5mm.
What is the water resistance?
It is rated to 200m with a screw-down crown, so it handles swimming and everyday water exposure.
What movement does it use?
Seiko's 6R54 automatic, with roughly three days of power reserve when fully wound.
Does it come on a bracelet?
Yes, it ships on a stainless steel bracelet. The lug width is 20mm if you want to swap straps.
Is the compass bezel functional?
The inner rotating bezel works as a rough sun-compass aid. It is friction-set, so treat it as a guide rather than a precision instrument.
Where is the SPB379 Prospex Alpinist GMT 39.5mm cheapest?
At Teddy Baldassarre, for $1,150.00, as of our latest check.
