Seiko has recently expanded their Seiko 5 Sports Field series to include two new references, each with a GMT function. A first for this line of watches following the popular series that included rotating 24 hour bezels last year, the GMT function allows for a secondary timezone to be easily read in a tidy field watch format. Whether choosing the silver SSK023 or the more rugged black SSK025, each balances functionality against a backdrop of timeless design.

As for the specifications of this watch, the Seiko 5 Sports Field series is a robust and reliable timepiece designed for everyday wear. Equipped with a 4R34 automatic movement, it offers a power reserve of approximately 41 hours and is equipped with 24 jewels. The watch incorporates practical functions such as a 24-hour hand for dual time display and a stop second hand function. Functionality is identical to the earlier Seiko 5 Sports GMT release, which means an independently adjustable 24-hour hand and “caller” GMT functionality. 

Its stainless steel case, measuring 39.4mm in diameter and 13.6mm in thickness, includes a curved Hardlex crystal and showcases Lumibrite on both hands and indexes for enhanced visibility. The watch has a water resistance of 10 bar and magnetic resistance of 4,800 A/m, making it suitable for various environments that really lives up to its field watch bona fides. Importantly, these watches feature a fixed 24-hour bezel in the style of a Rolex Explorer II, which naturally gives these watches a deeper tool watch vibe.

The SSK023 reference is a stainless steel watch with a corresponding bracelet. The SSK025 has a hard outer coating over stainless steel in black, with a watch band made from a matching black calfskin.

This pair of watches will be available at select Seiko boutiques and online beginning in January of 2024. They will be priced at $435. Seiko
