The De Bethune DB25 GMT Starry Varius pairs a second-time-zone display and day/night indicator with the brand’s starry titanium dial. It is a travel-watch evolution of the DB25 Starry Varius, related to the DB25 World Traveller introduced in 2016. De Bethune describes it as “a travel watch designed for those who move seamlessly between time zones.”

What is the DB25 GMT Starry Varius?

It is a hand-wound GMT watch in De Bethune’s DB25 Starry Varius family. The design brings travel-time functions into the Starry Varius format while retaining its miniature-sky motif. De Bethune’s journal describes the engineering challenge as fitting a GMT movement into the Starry Varius case without losing that visual signature.

The watch’s defining arrangement combines a 24-hour subdial, a day/night indication and a central blue titanium dial decorated to evoke a starry sky. Its time and date displays sit on curved rings around that center.

How do the GMT and day/night displays work?

Second time zone

The 24-hour subdial provides the GMT display, distinguishing the second time zone from the main time display. De Bethune specifies a silver subdial with two-tone decals. The published material describes the indications but does not establish the setting procedure or adjustment controls, so those details should not be inferred from the dial layout alone.

Pagani Design GMT Automatic Mechanical Men's Watch Rotating Ceramic Bezel Stainless Steel Watch with Date Function Men's Sport Watch (Steel Band Black and Blue-3)
  • Pagani Design 1662 Men's Watch: Pagani Design GMT features a black dial, two-tone ceramic bezel, independent 24-hour hand and 24-hour scale bidirectional rotating outer ring, which can display the time in two time zones at the same time: the date display on the simple design dial creates a simple, high-quality appearance. (Note that the bezel of the red series is not made of ceramic)
  • Automatic watch: Equipped with an automatic movement, it mainly transmits kinetic energy through the natural movement of the wearer's wrist. It is self-winding, durable, and has a long kinetic energy reserve without the need for batteries.
  • Clear reading: Like all professional watches, the GMT watch is equipped with a self-luminous display to ensure excellent readability anywhere, even in the dark. The large hands and simple hour markers - triangle, circle, rectangle - are filled with luminous material, emitting a long-lasting glow.
  • 100 meters waterproof: The watch is waterproof to a depth of 100 meters. Do not put the watch in a hot bath. Waterproof for daily use, cold shower, hand washing, rain, splashing water, cold shower are no problem. It is not recommended to wear the watch in a hot bath. Water vapor will corrode the waterproof rubber ring, and most watches do not have water vapor protection.

Day and night

A microsphere made from rose gold 5N and blued steel indicates day and night. De Bethune says the decorative technique is comparable to the one used for its spherical moon-phase display.

What does the dial look like?

The dial is built in layers: a curved hour ring and a curved date ring frame the central sky display, while a rose-gold curved minute ring adds another track. At the center, polished blue titanium carries white-gold pins and radiant silver microlight decoration, with a polished rose-gold sunburst insert. The 24-hour subdial sits within this arrangement rather than replacing the main time display.

What the published specifications do—and do not—tell you

The dimensions and display description establish the watch’s layout, but not how it wears or performs in person. The available manufacturer materials do not establish wrist presence, comfort, legibility in different lighting, operational ease, accuracy in use, price, production status or regional availability. Those points require direct observation or current market confirmation.

For a like-for-like travel-watch comparison, useful axes include case dimensions, water resistance, winding method and reserve, the way the second time zone is displayed and adjusted, legibility, strap and clasp, and price and availability in your market. The specifications here describe only the DB25 GMT Starry Varius; no competing model figures are established.
