I've always had a thing for analog digitals, as the champagne dial AMW320 was strapped to my wrist through the early 90's.
Once I saw the Chronosport UDT I lusted after it to no avail. Prices are way too high for my liking, in fact there's a non working one on eBay right now that looks like it went through a meat grinder missing buttons with bidding already at couple hundred dollars.
I have the black PVD version AMW320 so I thought I would try and mimic the look of the UDT.
I aged the lume on the dial and hands and placed a colored filter over the LCD portion of the AMW320.
So far I'm digging the mod and I am on the hunt for pencil style hands that fit the Casio movement, if I'm able to find something suitable I will mod the watch further.
The watch I used is a beater work watch with dings and scratches so no remorse if I screwed it up.

Here's the modified AMW320
