From Holden’s Watch Desk research
Seiko Presage Cocktail Time SRE007 "Sky Diving"
The Seiko Presage Cocktail Time SRE007 "Sky Diving" (SRE007J1) is a dress watch from Seiko: a 30.3 mm stainless steel case, 10.9 mm thick and 37 mm lug to lug, with an automatic 2R05 movement and 50 m water resistance.
Going by its 37 mm lug to lug, it should sit within the flat top of a wrist of about 5.0 inches (12.8 cm) or larger.
Research found it at $575 list in the US (checked August 2026) and about $480–550 on the street (August 2026).

Will it fit?
A watch wears comfortably when its lugs stay on the flat top of the wrist. Here is the 37 mm lug to lug against the flat top estimated for common wrist sizes.
| Wrist | Flat top | Fit |
|---|---|---|
| 6 in 15.2 cm | 47 mm | Comfortable |
| 6.5 in 16.5 cm | 51 mm | Comfortable |
| 7 in 17.8 cm | 55 mm | Comfortable |
| 7.5 in 19.1 cm | 59 mm | Comfortable |
| 8 in 20.3 cm | 63 mm | Comfortable |

What the research found
These are the research’s judgments, scored against Holden’s priorities, not his own words.
Strengths
- The dial is the whole product and it is genuinely well made: a pressed pattern under several polished layers of transparent lacquer is a real manufacturing process, not a printed effect, and it is the same technique that made the men's Cocktail Time line famous
- Proportions are excellent and increasingly rare — 30.3 mm across, 10.9 mm thick, and only 37.0 mm lug-to-lug, which is a genuinely small watch rather than a shrunken men's case
- Mechanical, in a segment where nearly every competitor at this price is quartz — automatic with hand-winding, hacking seconds and an instant date
- Uncoated stainless steel case on this particular reference, so there is no plating to wear through over decades (unlike the gold-tone SRE010/SRE018/SRE020 siblings)
- Full Seiko service network, published technical guide and parts list, and a three-year factory warranty
- A real product story — each dial is tied to a named cocktail (Sky Diving here), which is a coherent brand idea rather than a colour chart
Weaknesses
- Box-shaped Hardlex, not sapphire — this is the recurring criticism of the whole Cocktail Time line and it matters more on a highly polished dress watch that will pick up desk marks
- Calibre 2R05 is a basic movement: 21 jewels, 21,600 vph, ~40 h reserve, and an official worn rate window of -35/+45 s/d. It is unregulated in any meaningful sense and Seiko documents replacing the movement at overhaul
- Solid case back with nothing to look at, so the mechanical content is invisible — the movement is a functional choice, not a display one
- 50 m water resistance and no documented screw-down crown means it is a wear-it-carefully watch
- Seiko publishes very little about this reference: no weight, no lume statement, no bracelet or clasp detail, no finishing description. Editorial coverage of the women's line is almost non-existent, which makes it hard to research and hard to resell
- 14 mm lug width narrows the aftermarket strap options considerably
