Seiko’s first GMT watches in the Presage Cocktail Time line are the SSK037, SSK039 and SSK041. All three share a 40.5 mm stainless-steel case and automatic Caliber 4R34; the choice comes down mainly to dial color, GMT-hand color and strap. The 4R34 is an office-style GMT: its central 24-hour hand tracks a second time zone and adjusts in one-hour steps, while the regular hour hand remains the main local-time display.
What separates the three Cocktail Time GMTs?
The core specifications are shared, so compare the details that change before choosing a reference. Seiko describes the SSK041 dial as ivory; the 2024 launch report calls it graduated honey yellow, reflecting different descriptions of its warm tone rather than an exact match in terminology.
| Reference | Dial and inspiration | GMT hand | Original strap and clasp |
|---|---|---|---|
| SSK037 | Light blue, pressed pattern and gloss finish; “Skydiving” | Blue | Stainless-steel bracelet; deployment clasp with push-button release |
| SSK039 | Dark-brown gradated dial, pressed pattern and gloss finish; “Rusty Nail” | Gold-tone | Black leather strap; tri-fold push-button release clasp |
| SSK041 | Ivory, pressed pattern and gloss finish; “Acacia” | Gold-tone | Dark-brown leather strap; tri-fold push-button release clasp |
Monochrome Watches’ June 6, 2024 first look connects the names to cocktails: Skydiving with rum, lime juice and blue curaçao; Rusty Nail with Scotch whisky, Drambuie and lemon peel; and Acacia with gin, Benedictine, Kirsch and lemon garnish. This is the article’s account of the inspirations, not a Seiko-verified recipe claim. [Monochrome Watches]
How the 4R34 GMT works
This is an office- or caller-style GMT, not a traveler-style GMT with an independently jumping local hour hand. The central 24-hour hand adjusts separately in one-hour increments and reads against the peripheral 24-hour scale. That lets you follow another time zone while using the conventional hour hand for local time.

Seiko USA lists automatic winding with manual-winding capability, 24 jewels, a frequency of 21,600 vibrations per hour and an approximately 41-hour power reserve. A date calendar and screwdown see-through caseback are also specified. Seiko USA says the 24-jewel movement, visible through the caseback, beats at 21,600 vibrations per hour and has an approximately 41-hour reserve. [SSK037 specifications]
Shared size and practical considerations
Each model measures 40.5 mm across, 12.8 mm thick and 47.5 mm from lug to lug. The case is stainless steel, the box-shaped crystal is Hardlex, and water resistance is rated at 5 bar (50 m). Seiko lists a 20 mm lug width for each model. These dimensions are useful starting points for judging wrist fit, but they do not establish how a particular watch will wear on an individual wrist.

- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
- Crystal: Hardlex is specified; the listings do not establish sapphire-equivalent scratch resistance.
- Water resistance: 50 m is not a reason to treat the watch as a dive watch. Match water use to Seiko’s guidance for the model.
- Strap changes: The 20 mm lug width may help when looking for alternatives, but width alone does not confirm end-link or clasp compatibility, or that a specific aftermarket strap will fit.
Prices and release context
Prices differ by region and listing context, and can change. Seiko USA displayed $625 for the SSK037 and SSK039; the captured SSK041 page did not show an independently visible price. Seiko’s India Cocktail Time GMT lineup listed all three at INR 70,000. These are separate regional listings, not a universal price comparison.

Monochrome Watches reported on June 6, 2024 that the trio would join the permanent collection and become available from July 2024 at a launch price of EUR 600. That figure is historical launch context, not a current worldwide price. [Monochrome Watches, June 6, 2024]

Which reference should you choose?
- Choose SSK037 if you want the light-blue dial, blue GMT hand and steel bracelet.
- Choose SSK039 if you prefer the dark-brown dial, gold-tone GMT hand and black leather.
- Choose SSK041 if the warm ivory-toned dial and dark-brown leather are the combination you want.
All three use the same basic movement and case dimensions, so the decision is chiefly about appearance and the supplied strap or bracelet. If possible, check the 47.5 mm lug-to-lug length and 12.8 mm thickness on your wrist before buying.
