The Seiko Superior SRP495 — better known to collectors as the Stargate II — is a discontinued automatic dive watch with a bold black dial, black ion-plated unidirectional bezel, and the reliable in-house 4R36 calibre. It suits everyday wear in Australia as much as weekend water sports: tough tool-watch styling, 200 m water resistance, and a full steel bracelet without dress-watch fuss.
What stands out on the wrist is legibility. Large luminous indices and hands, a clean black dial, and the signature “chevron” style pip at 12 make the SRP495 easy to read in low light. Day and date sit at 3 o’clock under a magnifier. The crown is offset toward 4 o’clock with a coloured accent ring on many examples — a practical layout that keeps the case clear of the wrist bone.
Why the SRP495 Stargate II still gets attention
- Proven automatic movement — Seiko 4R36 with 24 jewels, hacking seconds, hand-winding, and about 41 hours of power reserve when fully wound.
- Real diver hardware — screw-down crown, screw case back, unidirectional diving bezel, and 200 m water resistance.
- Hard-wearing crystal — Seiko Hardlex mineral crystal balanced for daily knocks.
- Collector nickname with a clear look — the Stargate II bezel marker and black-on-black contrast made this reference easy to spot in the Superior / Mechanical diver line.
- Comfortable tool proportions — about 43 mm case diameter, roughly 12 mm thick on our listing data, ~46 mm lug-to-lug, 22 mm lug width.
Who it suits
Buyers who want a discontinued Seiko automatic diver with a darker, stealthier look than colourful Prospex special editions. It works as a first serious dive-style watch or as a rotation piece next to a dress automatic. If you prefer modern sapphire and slim cases, look at current Prospex lines; if you want the classic Stargate II face and 4R36 serviceability, this is the reference.

Frequently asked questions
What movement does the Seiko SRP495 use?
The SRP495 Stargate II runs on Seiko’s automatic calibre 4R36. It has 24 jewels, roughly 41 hours of power reserve, and supports hand-winding and hacking seconds so you can set the time precisely.
What is the water resistance of the Seiko SRP495?
It is rated to 200 metres (20 bar) with a screw-down crown and unidirectional dive bezel. That rating assumes the watch is in good service condition; pressure testing after battery-free mechanical service intervals is still good practice if you dive regularly.
Is the SRP495 suitable as an everyday watch in Australia?
Yes for most daily wear. Hardlex crystal, steel case and bracelet, and a robust automatic movement handle commuting and weekends well. Size is on the larger side at about 43 mm, so try photos against a known watch if you prefer smaller dress pieces.
How does the Stargate II differ from the original Stargate?
The Stargate II generation (including SRP495) moved to the 4R36 with hand-winding and hacking, and typically adds a day-date magnifier window. Earlier Stargate pieces used a non-hacking 7S-family movement. Cosmetics stay in the same bold black diver family.
Does the SRP495 have a sapphire crystal?
No. This reference uses Seiko Hardlex, a hardened mineral crystal common on many Seiko divers of its era. Hardlex is tougher than basic mineral glass; it is not sapphire.
