The 2024 Mido Ocean Star GMT Special Edition is reference M026.829.18.041.00: a 40.5 mm steel dive watch with a traveller-style GMT, 200 m water resistance and an additional blue textile strap. It is a different watch from Mido’s 44 mm Ocean Star GMT Special Edition of 2022, despite sharing the name.
What distinguishes the 2024 Special Edition?
The name can cause confusion: Monochrome Watches’ March 2024 introduction covers reference M026.829.18.041.00, not the earlier M026.629.11.041.00. The newer reference pairs a smaller case with a navy aluminum bezel insert and a steel bracelet, and comes with a blue textile strap. Monochrome’s 2024 introduction identifies the model and describes its design.
| Detail | 2024 M026.829.18.041.00 | 2022 M026.629.11.041.00 |
|---|---|---|
| Case diameter | 40.5 mm, per Monochrome’s 2024 specifications | 44 mm, per Europa Star’s August 2022 report |
| Bezel | Bidirectional, with navy blue aluminum insert and silver-colored 24-hour scale | Unidirectional, with blue ceramic insert |
| Dial and accents | Glossy navy dial with date at 3 o’clock | Blue dial with red accents |
| Bracelet and additional strap | Multi-link steel bracelet with diving extension; additional blue NATO-style textile strap | Steel bracelet and striped blue-red-white fabric strap |
The 2022 details are reported by Europa Star’s August 2022 article carrying Mido press-release copy. The two editions should not be treated as the same watch or as simple size variants.
How does the GMT work?
Monochrome describes the 2024 model as a traveller, or flyer, GMT. Its main hands show local time; a separate 24-hour hand, read against the bidirectional bezel’s 24-hour scale, indicates a second time zone. Mido’s product page describes the watch as displaying home and local time. This is the stated GMT layout; the available sources do not establish a hands-on test of its setting operation.

#1 Best Overall
- GMT Swiss Watch: The practical GMT function makes it possible to display two time zones simultaneously thanks to an additional hand that makes one complete revolution in 24 hours and uses a bezel graduated over 24 hours to indicate a second time zone.
- Movement: Automatic Mido Caliber 80 with Navichron balance spring which reduces magnetic interference and is remarkably robust against impacts and the effects of time. This caliber ensures exceptional autonomy of up to 80 hours.
- Water Resistance: This Swiss-made MIDO timepiece is capable of withstanding pressures of up to 20 bar (200 m/660 ft), and equipped with a screw-down crown, this watch offers optimal protection against water.
- Case Size: 44mm - Case Thickness: 13.38mm. Stainless steel case with blue ceramic bezel and Sapphire crystal with double sided anti-reflection treatment - Lug Width 22mm

The bezel’s 24-hour scale lets the wearer track the second zone relative to the main time display. The bezel is bidirectional and has a navy aluminum insert with a silver-colored scale, according to the 2024 technical specifications.
Case, movement and specifications
The 2024 edition measures 40.5 mm across, 13.4 mm thick and 46.99 mm from lug to lug. Its case is stainless steel, with a box-style sapphire crystal, screwed caseback and screw-down crown. Monochrome lists water resistance at 200 m; Mido’s US product page independently gives 20 bar/200 m.
