Seiko SKX013 Mod - low double dome Sapphire Crystal (Blue AR coating), Ceramic Bezel insert - Original Seiko 7S26 movement

This Seiko SKX013 was sent to me by a client. He had order all his parts from SeikoMods. The client wanted to change the crystal, insert & hands. The hands required a little work as they were sized for the SKX007/9 model and were a little to big for the dial / chapter ring.

Seiko SKX013 Mod – Crystal

The Crystal chosen by the client is a low double dome with blue AR coating. This is a sapphire crystal with the beveled edge.

The crystals from SeikoMods are great. I have never experienced any problems fitting theses and you can reuse the original crystal gasket without any issues with water resistance – I have received some crystals from client specifically with the SKX013. These can bind up on the gasket and it can be a struggle to fit – If this is the case I use a fine wet stone to clean the leading edge of the crystal.

Seiko SKX013 – Hand Mods

The hands chosen for this Seiko SKX013 mod are the SKX007 /009 style hands. These are a tad big for this watch, not fitting inside the chapter ring.

I have modified these hands to fit a Seiko SKX013 before. So, I was sure of the length to remove from the minute and second hand.

Bezel Insert – Mod

The ceramic insert mod a great upgrade you can make to your Seiko Diver. The ceramic insert is more hard wearing that the original.painted aluminum. Removing the original bezel insert is best done with a light solvent cleaner/remover.

It is easiest to work on the bezel once it is removed form the watch – To remove the excess glue from the bezel more solvent remover and plastic scraper does the job. A clean with acetone to ensure there is no residue left behind. The sticky tape can be applied.
