The Seiko Presage Cocktail Time GMT SSK037, SSK039 and SSK041 share the same core specifications: an automatic 4R34 movement, a 24-hour hand for dual-time display, and a 40.5 mm case. The clearest documented distinction is that Seiko specifies cow-leather bands for the SSK039J1 and SSK041J1; the extracted SSK037J1 specification does not state its band material. Seiko’s cited official specifications do not establish the exact dial-color differences, so compare verified model images before choosing by appearance.
What is the difference between the SSK037, SSK039 and SSK041?
Seiko lists all three as Presage Cocktail Time models. The full references on the cited product pages are SSK037J1, SSK039J1 and SSK041J1. Their movement, functions, case dimensions, crystal and water-resistance specifications match. The documented band distinction is limited: the SSK039J1 and SSK041J1 have cow-leather bands, while the extracted SSK037J1 specifications identify a 20 mm lug spacing but do not state band material.

Specifications are from Seiko’s SSK037J1, SSK039J1 and SSK041J1 pages.
Choosing by band
If you want a documented leather-band option, the SSK039J1 and SSK041J1 are the references for which Seiko specifies cow leather. The 20 mm lug spacing is useful when considering another strap, but check spring-bar and model compatibility for any replacement. The available SSK037J1 specification text does not support identifying its band material, so confirm the exact product listing or ask the retailer before buying if band type matters.

Choosing by appearance
Seiko describes the Cocktail Time collection as having “vibrant, glossy dials reminiscent of colorful cocktails,” but that collection description does not identify which dial belongs to each of these three references. The cited official text therefore does not settle their exact color mapping. Check Seiko’s model-specific imagery and the product reference on the seller’s listing rather than relying on an unverified color name.
How does the Cocktail Time GMT work?
Each cited model page lists a 24-hour hand for dual-time display, alongside the date and stop-seconds function. The 24-hour hand can indicate a second time zone while the main hands show local time. The pages do not establish that the local hour hand jumps independently, so do not assume the adjustment works like a travel GMT with a separately adjustable jumping hour hand. For exact setting and adjustment steps, follow the manual for the watch.
Rank #2
- Seiko Presage Cocktail Clock GMT
- Inspired by acacia cocktail
- Ivory graded dial with deep pressed pattern and gloss finish
- Hand shaped GMT in gold tone to look like a cocktail glass
- Automatic rewinding feature
Seiko specifies the 4R34 as automatic with manual winding, with an approximately 41-hour power reserve and 24 jewels on each of these three pages. These are manufacturer specifications, not a measured timekeeping or power-reserve test of individual watches.
What size are the SSK037, SSK039 and SSK041?
Seiko gives all three a 40.5 mm case diameter, 12.8 mm thickness and 47.5 mm lug-to-lug measurement. Those shared dimensions make case size a poor way to distinguish the references on paper. The 47.5 mm lug-to-lug figure can help when comparing the watch’s reach across your wrist, but fit also depends on wrist shape and personal preference; trying one on is the most direct check.

What does 5 bar water resistance mean here?
Seiko lists 5 bar water resistance for each reference. That is the stated rating, not by itself a detailed activity recommendation. The cited specifications do not explain suitable use in specific conditions, so check Seiko’s guidance for the watch and keep the crown and case in the condition required by its instructions.
