On Ali there are G-Shock adapters but most of them are plastic which would end up kinda off. But steel one ? Maybe ?

Also - automatic version have different, waffle dial. 

You could brush old case.
If it is NH3xx movement - sometimes you can have good deal on Ali on eBuy.
What case and bezel it is ?
and why you wanted to change it ?

SNK361 with dial from SNXS79 and upgraded movement to NH36A.

This mysterious watch. Sorry for pic but just finished putting it together.

Day-date (most of my watches have it) but World timer - yes I want one.

Omega Worldtimer shown here is my grail watch. If I ever manage to win at lotto or something I will buy one.

In my work I'm dealing with people from around the world in the same time (like customer is in South Africa, some support is in USA and manager in New Zealand) while I'm in Ireland.

Having world timer watch helps to find out what time is for person you are talking with.

Like create a paper weight from epoxy with parts inside it - that would be cool.
