Another addition to Ba111od’s accessible tourbillon story is written with the new Chapter 4.8 GMT Tourbillon Greenwich Limited Edition.

Press Release information with commentary in italics.

New: Ba111od Chapter 4.8 GMT Tourbillon Greenwich Limited Edition

The Ba111od Chapter 4.8 GMT Tourbillon Greenwich Limited Edition retails at SGD 9,600 / CHF 7,800 before taxes. Limited edition of 50 numbered pieces.


The novelty is a new dial variation to the Chapter 4.6 GMT Tourbillon 1920 Limited Edition released in 2023. Chapter 4.6’s 50 piece limited edition is now sold out, and this new Chapter 4.8 is offered also as a limited edition of 50 pieces. The watch is essentially the same, but what’s new is the sage green dial finished with sunray. The green brings a strong character to the watch. And the sunray finish adds a dimension to the dial, bringing tones of lighter and darker green into play. The GMT function is reinforced by an engraving of a world map on the GMT sub-dial located at 1 o’clock. This is also new, as the Chapter 4.6 does not feature a world map engraving. Again, adds more character. The dial layout is balanced by the aperture to show the tourbillon at 7 o’clock.

The same movement which is used in the 4.6 is also used in the 4.8. This is a movement developed and manufactured by Olivier Mory. The same crystal NFC technology is embedded in the watch’s sapphire crystal.

Pricing remains competitive, though the retail price has slightly increased from CHF 7.5k for Chapter 4.6 to still very modest CHF 7.8k for Chapter 4.8. Still the least expensive Swiss made tourbillon, now with GMT, in the market today.

Release information

BA111OD is a luxury brand that aims to be accessible. Following the success of the Chapter 4.6 GMT Tourbillon 1920 Limited Edition, which is now sold out, the brand is unveiling its latest innovation, the Chapitre 4.8 GMT Tourbillon Greenwich Limited Edition, a combination of assertive and retro design. This very exclusive series of 50 numbered pieces features an elegant sage-green dial inspired by our beautiful Jura mountains, housed in a 44mm titanium case. The hand-wound mechanical movement, developed in La Chaux-de-Fonds in the heart of the Vallée horlogère, features a GMT function with world map engraving at 1 o’clock and a hypnotic tourbillon at 7 o’clock. A timeless timepiece that combines excellence and elegance at an unprecedented price.

The BA111OD Chapter 4.8 GMT Tourbillon Greenwich Limited Edition may be classic in its design, but it is certainly modern in its conception: it has a 44mm case in raw grade 5 titanium, with the crown always positioned at 4 o’clock. Powered by a hand-wound mechanical movement with a 105-hour power reserve developed by the brilliant watch designer Olivier Mory, it has a sunray sage-green dial with a GMT counter featuring a magnificent world map engraving at 1 o’clock and a tourbillon at 7 o’clock. As with previous BA111OD models, this timepiece also incorporates NFC technology in the watch’s sapphire crystal, providing a personalised user experience that strengthens the special bond with its customers. A feat that the brand was the first to offer, and one that demonstrates its commitment to innovation. Finally, the timepiece is adorned with an elegant crocodile-style leather strap (an ethical choice), fitted with a folding clasp.
