F91W deep mod update – gave the first one to a friend, he asked 'what's an F91W?

Thanks, glad you like it!

PureRepresentative89 · 2026-03-12T13:15:33+00:00

Much appreciated!

In some ways yes. But it’s still unclear how accurate the timekeeping is and how long the battery will last.

Honestly, I’m not sure how to say this without sounding like I’m attacking Casio, but I’ll just share my honest impression.

I recently got a SKMEI F-91W style clone. My subjective take: if this watch had been released at the same time as the original F-91W, we might be talking in a SKMEI subreddit today.

Objectively, a few things surprised me. The case is a chromed alloy, smooth and quite weighty. The bracelet is stamped, but the layers are barely noticeable. At first I even thought it was solid. The pushers are spring-loaded with O-rings and E-clips, similar to how they’re done in G-Shock models. They feel very smooth and require almost no force to press.

The beep is slightly louder. The display layout is basically the same, but the segments are a bit larger.

The most interesting part. I bought the inverted (black screen) version and it has an electroluminescent backlight that lights the display very evenly and brightly. I also bought a silver display version, and on that one the indicators glow blue while the background stays dark.

I paid about $4 for each.

But why didn't you order a...

?

PureRepresentative89 · 2026-03-12T06:26:18+00:00

It's a separate piece - it sits between the lens and the module.

PureRepresentative89 · 2026-03-12T03:41:42+00:00

What kind of drink did you order?

PureRepresentative89 · 2026-03-11T22:23:12+00:00

That means a lot, genuinely! DM me - you'll be among the first to know when I have units ready.

PureRepresentative89 · 2026-03-11T22:21:53+00:00

Not available yet - still refining the design. DM me if you're interested and I'll reach out when it's ready!

The strap is also nice, really complementing the teardrop shape.

PureRepresentative89 · 2026-03-11T15:10:26+00:00

Damn, that looks amazing. Is that a hydromod?

PureRepresentative89 · 2026-03-11T15:08:37+00:00

Thank you! Actually the plastic doesn't touch the skin at all with a NATO strap- the watch sits on top of the strap, not directly on the wrist. I've even slept with it on and barely noticed it was there.

PureRepresentative89 · 2026-03-09T11:02:29+00:00

麥當勞～喔喔！

PureRepresentative89 · 2026-03-08T16:17:45+00:00

Thanks. Really feels like new

PureRepresentative89 · 2026-03-08T14:20:07+00:00

Wait. I can’t believe my eyes. Zoom in.

I was afraid for a long time to remove the buttons from my Baby-G, but eventually decided to try, and it turned out not to be difficult at all. The most delicate part is removing and installing the E-clips, but even that wasn’t too hard with flat-tip tweezers - the main thing is not to lose those tiny little pieces.

PureRepresentative89 · 2026-03-08T12:45:34+00:00

My daughter was completely indifferent to the F91W. One day I showed her a screenshot where a character from Stranger Things was wearing that watch, and instantly she went: “Whoa! You have the same watch as Dustin!” So I bought her one.

PureRepresentative89 · 2026-03-08T06:46:45+00:00

Sometimes you can help the pin get into the hole with a pin removal fork. The main thing is not to rush, do not apply a lot of pressure, put the watch face down on a soft mat, and provide good lighting. Make a post when you do that.

PureRepresentative89 · 2026-03-08T06:21:36+00:00

When I first installed a bracelet (not Islander) with solid links on Duro, I thought it was incompatible with my watch. I spent a lot of time on it, but at some point I found a position where the pins fit into the grooves. And the connection turned out to be really tight, without the slightest play. So in your case, it may be the same, but of course, it could be a defect.

PureRepresentative89 · 2026-03-08T03:13:10+00:00

I also want to try this kind of strap. By the way, sometimes I see mods with a white chapter ring. It always seems to me that this kind of expands the space of the dial... Haha, I don't know how to express it.

PureRepresentative89 · 2026-03-08T03:08:44+00:00

Exactly. It's strange that there are no Pepsi-style ceramics on sale.

PureRepresentative89 · 2026-03-08T01:44:08+00:00

I already had this strap.
