The clear documented difference is the band: the SPB313J1 and SPB315J1 come on stainless-steel bracelets, while the SPB317J1 comes on a silicone strap. Seiko’s U.S. product page lists the SPB317J1 at USD 900; it does not establish a current price or availability for the other two references.
How the three references differ
Seiko’s 2022 Prospex brochure identifies all three as recreations of the 1968 diver’s watch. It documents their band configurations as follows:
| Reference | Band listed by Seiko |
|---|---|
| SPB313J1 | Stainless-steel bracelet |
| SPB315J1 | Stainless-steel bracelet |
| SPB317J1 | Silicone strap |
That is the model-specific distinction established by the brochure. It does not document other differences between the references, so claims about variation in finishing, comfort, or performance would go beyond the available specifications. Seiko Prospex 2022 brochure
What they share
The brochure lists the same main specifications for the trio:
Recommended Free Tools
#1 Best Overall
- Seiko 6R35 automatic movement
- 41.0mm case diameter
- 200m diver’s water resistance
- Curved sapphire crystal with anti-reflective coating on its inner surface
- Unidirectional rotating bezel
- Screw-down crown and screw case back
Seiko ties the design to its 1968 diver’s watch and describes crown protection and a slim profile as elements of that design. The brochure says the original watch was intended for professional divers who needed reliability, accuracy, legibility and durability; that is Seiko’s historical design description, not a claim of independently verified performance for these three modern references.
SPB317J1 specifications
Seiko’s U.S. product page provides a fuller specification list for the SPB317J1:

The precision figure is Seiko’s stated specification, not the result of an independent accuracy test. Seiko’s U.S. page lists the SPB317J1 at USD 900; the regional listing is not a guarantee of price or stock. Seiko SPB317J1 U.S. product page
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Choosing between them
If you prefer a stainless-steel bracelet, the brochure’s documented options are the SPB313J1 and SPB315J1. If you want the silicone-strap configuration, it identifies the SPB317J1. The listed diameter, movement and 200m diver’s rating do not distinguish one model from another. The sources do not establish current regional prices for SPB313J1 or SPB315J1, nor do they provide hands-on comparisons of wear, accuracy in use or diving performance.
