The Seiko Prospex JAWS 50th Anniversary Limited Edition SRPL81 is a 200-meter Prospex Sea diver with a 4R36 automatic movement, sapphire crystal, ceramic bezel display and a film-specific blue-and-white dial. Seiko says production is limited to 5,000 pieces. Its 45 mm case and 47.7 mm lug-to-lug span make the dimensions important to check before buying, while the JAWS graphics and engraved caseback supply the collectible appeal.

JAWS design details
Dial and bezel
Seiko USA describes a blue-and-white gradient, or ombré, dial pattern based on a memorable scene from the film. The JAWS logo is positioned at six o’clock. A blue ceramic display on the unidirectional bezel carries the diver-style timing scale.
Caseback and presentation
The caseback depicts the Orca and a shark’s dorsal fin and includes an individually engraved production serial number. Seiko USA also lists a JAWS 50th Anniversary collector’s box. Design and packaging details are shown on the Seiko USA product listing.

How the dimensions translate for buyers
On-wrist footprint
The 45.0 mm diameter, 13.2 mm thickness and 47.7 mm lug-to-lug measurement place the SRPL81 in large-diver territory by conventional sizing. Lug-to-lug is especially useful when checking whether the case will extend beyond the wrist; it is not a substitute for trying the watch on.
Strap compatibility
The 22 mm lug distance gives a clear starting point for replacement straps. Seiko supplies silicone, and any alternative should be confirmed for 22 mm fit and suitable spring-bar or clasp hardware before purchase.
Rank #3

Movement and diving equipment
4R36 automatic
The 4R36 winds automatically and by hand, offers approximately 41 hours of reserve and includes stop-seconds for setting the time precisely. Its day/date display adds everyday utility, while 24 jewels are part of Seiko’s stated specification.
Water-resistance package
Seiko rates the watch to 200 m / 660 ft as a diver’s watch. The package includes a screw-down crown, screw case back, unidirectional rotating bezel, sapphire crystal and LumiBrite on the hands, indices and bezel. The rating is a stated factory specification; it does not replace appropriate inspection and servicing after impact or seal work.
Rank #4

Price and availability
Seiko’s US SRPL81 product page lists a price of USD 795. That is the manufacturer’s displayed US price, not proof of a current transaction price in every market. The Seiko USA store page displayed “Notify me when in stock” when consulted, so stock status is volatile. Check the current manufacturer page or an authorized dealer immediately before ordering, and confirm seller, condition, authenticity, serial number, collector’s box and warranty coverage.
Who this limited edition suits
- Film collectors: the dial gradient, six-o’clock JAWS logo, shark-themed caseback, serial engraving and collector’s box are central to the proposition.
- Diver-watch buyers: the specification combines 200 m diver’s water resistance, a unidirectional bezel, sapphire crystal, screw-down crown and LumiBrite.
- Large-watch wearers: the 45 mm diameter and 47.7 mm lug-to-lug should be treated as meaningful fit checkpoints.
- Buyers seeking a compact or understated daily watch: the dimensions and overt film graphics may be less suitable than a smaller, non-themed Prospex model.
What to verify before buying
- Confirm that the reference is SRPL81, not another Seiko JAWS or Prospex edition.
- Check the live US price or local authorized-dealer price; the USD 795 listing can change and does not establish secondary-market value.
- Ask whether the individually numbered caseback, JAWS collector’s box, warranty documents and original silicone band are included.
- Measure your wrist against the 45.0 mm diameter, 13.2 mm thickness and 47.7 mm lug-to-lug dimensions.
- For a used example, verify crown operation, bezel alignment, crystal condition, water-resistance history and authenticity before relying on the 200 m rating.
The Bottom Line
The SRPL81 is a technically specified 200 m Prospex diver wrapped in an unmistakable JAWS commemorative design. Its strongest reasons to buy are the 5,000-piece production, film-specific detailing and sapphire-equipped 4R36 platform; its key practical question is whether the 45 mm case suits your wrist and whether a genuine, complete example is available at an acceptable current price.
