Seiko “Sea Urchin” SNZF series 15 and 17

The Seiko SNZF17 - part of the Seiko 5 Sports watches family and also called the “Sea Urchin” - can be seen as a very afforable diving watch with a similar style to the Rolex Submariner. The reference SNZF17 has a black bezel insert and a black dial, whereas the SNZF15 has a “Pepsi” (blue and red) bezel and dark blue dial.

This watch can be for many an ideal balance between price and style: the diameter of the SNZF model is 41mm and it is 13.2mm thick, making it a great fit for most wrists. It is powered by the reliable 7S26 automatic (self-winding) mechanical movement, offering a day-date complication. The water resistance of the Seiko “Sea Urchin” is 100m, making it suitable for surface swimming.

Despite its similar case style with the Rolex Submariner, the SNZF models have their own identity: the lumed hands and dial have a totally different design. They are protected by a hardlex mineral crystal, and will glow in the dark for hours. This is what we all love about Seiko watches : they have their own story and will never be blatant copies of other brands/models.

Once again Seiko offers a great and affordable alternative to more luxurious models such as the Rolex Submariner. If you do not like the Oyster-style stainless steel bracelet, the standard 22mm lug width will allow you to easily find alternative straps. The Seiko SNZF17 and SNZF15 can be found on the used market for less than $200.
