Why it scores as it does
Proportions and movement are computed from specs. Design details and functions are judged from the brand's official images. How we score
Lug-to-lug is neither published nor measured for one of the two watches, so there is not enough data to score.
Proportions— / 30
- Case diameter12 / 12Same size

Design signatures— / 40
- Two-colour 24-hour bezel12 / 12Two-colour 24-hour bezel with a 24-hour scale and a pointer triangle at 12 in the official images; the blue and black version is the closest to the original's colours.
- Blue GMT hand on a black dial8 / 8Blue arrow-tipped 24-hour hand on a black dial in the blue and black version. The other versions use red or green hands.
- Mercedes hour hand6 / 6Circle-and-spokes hour hand and a broad minute hand with lume, visible in the official images.

Functions and materials— / 20
- Complications4 / 8Date and a 24-hour GMT hand, like the original. Reviewers disagree on how the GMT hand works: one says the earlier movement did not have a true-GMT hand stack, another says the current movement has an independent hand.
- Bezel action4 / 4The brand lists a bi-directional bezel for a second time zone, and two reviewers describe a 24-click action, as on the original.
- Case and bezel materials2 / 4Brand states 316L steel. The brand does not state the bezel insert material; one reviewer calls it ceramic. The original uses a Cerachrom ceramic insert.

What reviewers and owners say
Reviewers
From 2 reviews we read or watched.
Both reviewers find the watch well made but unremarkable next to other GMT-Master-style watches. They like the smooth 24-click bi-directional bezel, the sapphire lens over the date, the polished case sides and the five-link bracelet with a milled clasp and micro-adjustment; one calls the bracelet excellent and the other calls it well made.
The main reservations are the movement and the fit. The two reviewers name different movements (an earlier Peacock 3032 and a later Seiko NH34), and one says the earlier hand stack is not a true GMT. The case is flat and the lug-to-lug is long, and the reviewer with the smaller wrist finds it uncomfortable. One reviewer saw a slight bezel misalignment and a crown that was slow to thread on his sample.
Good
- Sapphire crystal with a lens over the date
- 24-click bi-directional bezel praised for its action
- Five-link bracelet with a milled clasp and micro-adjustment, praised by both reviewers
- Crown guards and polished case sides
- Four bezel colourways
Less good
- Reviewers name different movements, so what is inside depends on the build
- Flat case and a lug-to-lug around 47 mm, uncomfortable for one reviewer on a smaller wrist
- The brand's movement and water resistance statements are not confirmed by all reviewers

Earlier versions
- Earlier build: A review of an earlier build names a Peacock SL3032 movement, which the brand listing still states. A later review says the current build uses a Seiko NH34 and that the earlier one had a Hangzhou 6460 GMT movement. The brand listing does not mention a change.
