G-Shock G-B001MVA Jason

After a week with this black‑and‑red Jason, I’m very happy I bought it. The wings hug my wrist, the large buttons are nice to use, and lifting off the smoky mask reveals a steel look I loved wearing too.

4.4 / 5 GOAT Reviews score

Best for:Collectors who like the round Jason design and a removable outer bezel
Not ideal if:You want a slim watch or a screen that is easy to read in all light. I found the dark screen hard to read during the unboxing.

From my review

Review Details

I wore the G-B001MVA-1 on my roughly 7-inch wrist for a week. I loved the fit and both bezel looks. The dark screen was the main trade-off.

What I liked

  • The wings under the strap help it hug my wrist for a snug, comfortable fit.
  • I wore it with the smoky mask off for a day and loved the brushed steel beneath.
  • The large buttons are nice to use, and the black-and-red finish is the version I wanted.
  • I enjoyed using Bluetooth to set the time accurately. The animated bars add movement alongside the seconds.

What to know

  • The dark screen was hard to read in some light during my unboxing, especially when checking alarms.
  • The app asking for Always location access annoyed me.
  • I would choose another watch for volleyball. I worried a direct hit could knock the mask loose, but I have not tested that.
