I keep seeing 200m WR mods...but every once in a while I see one where the maker has used a dial that specifies 300m WR. Is this done with a different gasket? Where is a good source for cases/backs/crystals/gaskets that can be modded into a 300 meter watch?

Thanks to all for the insight! It has certainly led me down the rabbit hole! But I am having a wonderful time down here! New question then...is there a quality Seiko (or other) GMT caliber out there with excellent value? What would you recommend?

Nanuq....thanks...I see knock offs and always wonder...and then I don't spend the money...thumbs up! If I make a mod as a gift and tell them it's safe to swim/snorkel/dive, I don't want a family member to get pissed at me.

Nanuq...Thanks for the info! I usually research something forever before I take the plunge into doing it. I'm one step closer to jumping in with both feet. Question though...how I make a 300m WR piece, and not just one that says it on the face?

I have recently discovered the world of Seiko mods. I am super interested in getting into this as a DIY hobby...what actions to buy...where? cases? crystals? straps? etc... etc... But...I am really intrigued with the idea of getting a nice Rolex clone movement and modding the outside in the same way...a unique watch that keeps precise time (+/- 6 seconds per day....max -10/+15 seconds per day, plus hacking) and does not require a safe to store it Also, any advice on where to find the seals and cases for a mod that provides outstanding WR? Advice/Thoughts please? Thanks!
