I 'm throwing the kitchen sink at the Diver One, I love the case shape, just like the old subbie but a bit thicker like the double red and the 40mm size is ideal for everyday wear.
The water resistance will now be 500m so that means a larger case back gasket, (1mm) slightly thicker case back and extra crown and tube gaskets (X4).
I'm adding a working Heliox Escape Valve so it will be the perfect chamber watch, small light and comfortable, being quartz it will not stop if you don't wear it, this has been tested by me and the deepest test was 154m
The Ronda movement will now be the gold plated 5 Jewel 715SM and this one has the End Of Life indicator and longer battery life so many people have asked for, as the keyless works are stiffer the movement will be housed in a metal holder.
The lume is now Grade A Superluminova.
The insert will stay Aluminium and this is not to save money as some people may think, I need the colour shades to match the dials and because the Diver One is a work horse watch it gets ridden hard, the diver one stainless steel was a very popular watch at work but I saw one cracked off a handrail and it smashed the ceramic insert, I've had a few back for repair also, I don't think ceramic is ideal in working conditions.
I hope you appreciate the improvements as most have come about from my workmates wearing them for work and of course feedback by WUS members.
