The Prospex Turtle Pepsi, seen from the bench

The Seiko Prospex Turtle Pepsi is a professional diving watch with a 42.6 mm stainless steel case and 13 mm thickness, featuring a distinctive red and blue Pepsi rotating bezel.

The 22 mm lug width accommodates standard sport watch straps and maintains balanced proportions with the case.

Frequently asked questions

What is the lug width of the Seiko Prospex Turtle Pepsi?

The Seiko Prospex Turtle Pepsi features a 22-millimetre lug width. This measurement is determined by the spacing between the spring bar attachments on the case and is compatible with premium artisanal straps available in leather, textile and rubber.

Which strap pairs best with the Prospex Turtle Pepsi?

The choice depends on intended usage. For formal and everyday wear, a vegetable-tanned leather or alligator strap offers sophistication whilst respecting the watch's diving heritage. For aquatic environments, FKM (Viton) rubber ensures total waterproofing. Polyamide NATO straps are ideal for summer and tactical applications.

How do you change the strap on the Prospex Turtle Pepsi?

Strap replacement is straightforward: position the watch sideways, locate the attachment pins on the case (typically small metal pins), use a spring bar tool to compress the internal spring and extract the old strap. Insert the new strap by aligning its ends with the designated holes and verify spring engagement before wearing.

Does the Prospex Turtle Pepsi accept 22mm aftermarket straps?

Yes, the Prospex Turtle Pepsi is fully compatible with 22mm aftermarket straps. Artisanal straps in leather, rubber and textile produced by specialists fit perfectly onto the original attachment pins without case modifications.

How long does a leather strap last on the Prospex Turtle Pepsi?

Leather strap longevity depends on wear frequency, water exposure and tanning quality. A vegetable-tanned leather strap properly maintained lasts 3-5 years with daily wear. Regular exposure to saltwater or chlorine accelerates degradation; periodic freshwater rinsing and drying significantly extends useful life.
