Description

After the rugged coin edge bezel I now also have a “Deepsea” bezel (for the SKX-divers and Seiko Sports with SKX-case, 42mm). The name Deepsea is based on the Seiko Tuna, the shape comes from the Tuna-bezel. Those Tuna watches are suitabel for depths up to 300 and even 1000m (so Deep-sea). Teh Tuna watches have body-protectors that also protect the bezel, turning the bezel is done with gloves and by gripping the bezel on the top/edge, so there is the grip area.
The bezel gasket comes installed, I suggest you grease is a bit before installing it on the watch case.

The bezel also comes with one of my improved circle-shaped double sided tape from 3M,, this can be used to attach a bezel insert.

You can use a nice flat bezel insert to change the look of your watch: (aluminum, sunray brushed steel, ceramic, lumed ceramic-version 1 ) and lumed ceramic version 2).
Or one from another source, inner diameter is 31.5mm and outer diameter is 38mm.
The 3M round can also be used for a sloped design bezel insert, beware that you also need a higher, stepped type of sapphire when you use a sloped bezel insert.

If you are considering changing the bezel insert of your SKX-diver or 42mm Seiko Sports with SKX-case, I suggest replacing the complete bezel and put the insert in the replacement bezel, this way you can conserve the OEM bezel (those cost around 70 euros, so a new bezel+insert = cheaper than a new OEM bezel)

I do not install the inserts in the bezels, it is best to first install the bezel on the watch, and then install the insert, aligned with the 12.
