The Orologi Calamai GMT Automatico is a 39 mm automatic watch with a caller-style GMT, a rotating 24-hour bezel and a restrained aviation-inspired design. Orologi Calamai currently lists it at €2,400, but marks it sold out and available on request. Its published specifications are appealingly compact; a few details, including thickness, power reserve and the aircraft behind its turbine-derived case material, differ between the brand and a 2025 hands-on review.
What the GMT Automatico is—and how its GMT works
Orologi Calamai describes the watch as an aeronautical instrument for pilots and travelers. The Sellita SW330-2 Top Grade movement provides an office, or caller, GMT: according to Monochrome Watches, the GMT hand can be set independently in one-hour increments. The wearer can use it to follow a second time zone while reading local time from the main hands. Its bidirectional 24-hour bezel adds another way to track a zone, as described in the review.
This is not the same setup as a traveler GMT that jumps the local hour hand to adjust to a new time zone. The distinction matters if you travel frequently and want to change local time without stopping the watch: the available sources describe the Calamai as a caller GMT, not a local-hour-jumping travel GMT.

A compact case, with an aviation-inspired finish
The manufacturer gives the case as 39 mm across, 47.5 mm lug to lug and 10.5 mm thick. Monochrome reports the same diameter and lug-to-lug but gives thickness as 10.8 mm with the crystal. Those figures suggest a relatively compact profile on paper, though dimensions alone cannot establish fit or comfort on a particular wrist.
Monochrome describes a brushed-and-polished case, a black ceramic bidirectional 24-hour bezel, sapphire crystal and screw-down crown. Its account also notes a multi-level textured black dial, luminous indices and hands, and a skeletonized GMT hand. These are details reported by the reviewer, not measurements or observations from an independent examination here.

- BLUE DIAL: this handsome men’s watch features a striking deep blue dial with luminous dial indicator hands and markers and date calendar to keep you organized
- BLUE & BLACK BEZEL: with a 24-hour bezel and easy-to-read fourth hand, this GMT watch helps you keep time as you travel

The review describes a solid caseback engraved with a turbine serial number and an aerobatic aircraft image. The provenance claim is inconsistent: Orologi Calamai’s current page identifies an F-104 Starfighter turbine, while Monochrome identifies a Panavia Tornado turbine. The model-specific claim cannot be reconciled from these sources, so the secure takeaway is simply that the brand presents turbine material as part of the watch’s aviation story.
How to judge it as a travel watch
The watch’s appeal rests on a combination of modest case dimensions, a mechanical caller GMT and a 24-hour bezel. That configuration suits someone who wants to keep a second time zone visible without a more overtly technical or oversized pilot-watch look. The bezel provides an additional reference, but using it effectively depends on the wearer understanding its 24-hour scale and aligning it to the zone being tracked.

For frequent travelers, the caller-GMT distinction is a practical trade-off: a jumping local hour hand is generally more convenient for resetting local time after landing. For someone who primarily wants home time displayed while adjusting the main hands for local time, the Calamai’s described arrangement may fit the use case. Neither source provides a controlled comparison with competing watches, an independent accuracy test, or a comfort test.
Price, availability and buying checks

Orologi Calamai sums up its stated approach this way: “We wanted to make an aeronautic instrument, favouring function over form, from which comes its beauty in simplicity.” The watch’s GMT hand, 24-hour bezel and aviation references reflect that intention, while the black dial and case dimensions keep the presentation relatively restrained.
