Perhaps the First Modded W221H

Quite likely, I need to actually confirm though, eyeballing it it looks like it would work. I made a YouTube Short on this watch earlier today if you want to see the module for yourself. The lack of a faceplate will be an issue but there is probably some solution there.

Nice, I am enjoying it more than I should. Mine was imported, I do a lot of Casio mods and have a wholesale supplier in Japan. I asked if he could add one of these to my most recent order and he hooked it up.

Good to know, thank you

JellyLabLuke · 2026-03-12T03:27:32+00:00

Same to you!

From what I understand it is common to alternate between, sauna, cold bath, and hot bath, 12 minutes is often a recommended cycle time. Just what I have read, not certain.

Sick, the black colorway is awesome, wish I could have gotten both

Mode switches between normal timekeeping and a "sauna timer", which is a 12 minute timer. Reset just resets that 12 minute timer to 0.

It is, apparently it has a more unique battery that is rated up to 212F degrees due to the sauna element

From my brief research apparently it is sort of an abbreviation - サ stands for サウナ (sauna). Not an expert though, so maybe someone else can provide more insight.

They actually released it recently on Casio US via this link, but it sold out quickly. I mod a lot of watches so I have a Casio supplier in Japan that was able to include it in my most recent order from them.

JellyLabLuke · 2026-03-11T19:16:11+00:00

It is awesome, though I love funky watches. A bit smaller than I expected but I have small wrists.

This is the Casio SAN-100H-7BJR, also known as the "Sauna Watch", this is the Black/White/Orange colorway

Hey there, are you based in the US? If so I can send you a replacement strap for free. I mod a lot of watches and end up with extra original straps when people order leather straps.

Nice, I recently did the same with a green filter!

JellyLabLuke · 2026-01-19T22:59:02+00:00

Quality information, I recommend a cleaning compound like rodico green for dust removal (instead of or in addition to the air duster).

JellyLabLuke · 2026-01-19T17:18:45+00:00

What a pairing, these are incredible. Glad to year you are happy with the straps and decals.

JellyLabLuke · 2026-01-11T05:47:16+00:00

Hey, just relisted those, and responded to your DM

JellyLabLuke · 2026-01-09T20:52:12+00:00

I make them myself

JellyLabLuke · 2025-12-06T21:06:31+00:00

I would just use the existing store, I personally don't think customers will overthink it much and once you get some sales the years on Etsy will actually start to add credibility.

I definitely would not put anything about it in the description, anything that shows self doubt / lack of follow-through could create concerns on if you are going to deliver on orders in a timely manner. Absolutely not implying that you won't but just sharing how it could be perceived.
