Seiko Prospex Alpinist Mechanical GMT Black Dial Watch

The Seiko Prospex Alpinist Mechanical GMT Black Dial Watch is perfect for lovers of the great outdoors. From the Land series of watches, Alpinist was first launched in 1959 exclusively for the Japanese market. However, it became so popular amongst Seiko fans that it was launched globally. The modern Alpinist has an upgraded specification. This includes a longer power reserve of 72 hours and an upgrade to a sapphire crystal.

Case, Dial, GMT, Compass, Strap

Firstly, ever practical, the 39.5mm stainless steel case has a super-hard coating which gives it shine and strong scratch resistance. Secondly, the bezel has a 24-hour display with the red 24-hour hand a feature of this watch. The black dial has the Alpinist’s signature arabic figures and hour markers (view blue dial version here). Additionally, Lumibrite on the hour markers ensures the dial is legible and easy to read. Similarly, the hands are also coated in Lumibrite. Furthermore, an inner rotating ring displays a useful compass. This is adjusted using a crown located at 4 o’clock. Additionally, a date window at 3 o’clock is a useful feature.

Finally, a black calf leather strap with secure folding clasp completes the look.

Movement

Water resistant to 20 bars, the Alpinist is a practical timepiece with a casual aesthetic. Equipped with an automatic 6R54 calibre, the Seiko Prospex Alpinist Mechanical GMT Black Dial Watch is accurate to +25 to -15 seconds per day. This in-house built calibre is the first mechanical GMT movement in a Prospex watch to have a three-day power reserve, allowing tracking of two different time zones at the same time. A great all-round watch for the active man: a two year manufacturer’s warranty guarantees peace of mind.
