The CHANEL J12 GMT H3101 is a 41 mm matte black ceramic-and-steel watch with a second-time-zone function, date and 100 m water resistance. CHANEL’s published specifications make it possible to assess what the watch offers on paper; they do not establish how it wears, performs or holds up in use. The brand’s US page lists it at $10,100 and marks it unavailable, while its UK page lists £8,250 and offers an availability notification. Those are regional page states, not a guarantee of market-wide stock.
What the CHANEL J12 GMT H3101 is
The H3101 is the matte black version of the 41 mm J12 GMT. CHANEL describes its case as matte black highly resistant ceramic and steel, paired with a matte black ceramic bracelet and a steel triple-folding buckle. The black lacquered dial has rhodium-plated numerals and a 24-hour time zone on the flange.
CHANEL says, “Every J12 is developed and assembled at the CHANEL Manufacture in La Chaux-de-Fonds, Switzerland.” That is the manufacturer’s account of the collection’s development and assembly.

#1 Best Overall
- 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.
- Satisfaction Guarantee: We will replace your product within 60 days without any questions; Pagani watch quality issues warranty for 1 year, 24-hour customer service, if you encounter any quality problems, please contact us immediately and we will do our best to solve the problem.
What the GMT function tells you—and what the listing leaves unclear
CHANEL lists GMT and a 24-hour time zone on the dial’s flange, indicating that the H3101 is designed to show a second time zone. The published function list does not explain the setting procedure or establish whether the local-hour hand can be adjusted independently. If that operation matters to you, confirm it with CHANEL or a retailer before buying rather than assuming a particular GMT mechanism from the label alone.
Matte ceramic, dimensions and water resistance
The combination of matte black ceramic and steel gives the H3101 a material and finish identity distinct from a conventional polished-steel sports watch. Its listed dimensions are 41 mm across and 10.38 mm thick. Those numbers help with a first-pass size comparison, but they cannot establish wrist comfort, how the bracelet drapes, or how the watch looks in person.
CHANEL lists water resistance at 100 m. That is a specification, not a report of independent testing or a substitute for checking the watch’s condition and care requirements. The listing alone does not establish suitability for a particular activity or how water resistance will fare over time.
Rank #2
- 38mm stainless steel case
- Day date window on dial
- Acrylic lens
- Stainless steel attachment
- Water resistant to 50m (165 ft): In general, suitable for short periods of recreational swimming, but not diving or snorkeling

- It may fit your shortlist if you want a black ceramic J12 with a second-time-zone display, date, and a 100 m water-resistance rating on the manufacturer’s specification sheet.
- Compare carefully if your decision depends on wrist fit, legibility in particular lighting, measured accuracy, durability in daily use, service costs, or value against other GMT watches. The available manufacturer listing does not answer those questions, and no like-for-like competitor comparison is established here.
- Verify before committing if you need immediate availability or a specific GMT setting behavior. The regional page states differ, and the listing does not describe the setting operation.
What this review can—and cannot—establish
The accessible primary evidence is CHANEL’s product listing. It supports a specification-based assessment of the H3101, but not hands-on conclusions about comfort, legibility, timekeeping, long-term durability, resale value or comparative worth. A 2013 aBlogtoWatch video review is identifiable by title and reviewer, but its page was inaccessible; its conclusions therefore cannot be verified here. No verified marketplace inventory is established.
