The Bōken Breacher is a 39 mm mechanical watch collection with three reported versions: a stainless-steel time-only model, a stainless-steel GMT, and a black DLC-coated GMT. The GMT models add a second-time-zone display; the time-only watch uses a different Sellita movement and has a shorter reported power reserve. The figures below come from the February 2025 launch report, so check Bōken’s current model listings for live specifications, price, and availability.
What is the Bōken Breacher?
The Breacher is a mechanical watch collection from Bōken. The brand describes it as “Built British. Ready for anything.” and says the watches are assembled in the UK by Horologium. That describes the assembly and brand positioning; it does not establish that every component is made in the UK. Bōken’s official site is the place to check its current product information.
Launch coverage describes a 39 mm case, 200 m water resistance, sapphire crystal with anti-reflective coating, exhibition case back, textured black dial, and 20 mm lug width. It also reports a three-link steel bracelet with a micro-adjustment clasp. These are launch-reported details, not a substitute for confirming the specification of the exact variant currently for sale. Time+Tide’s February 2025 launch report is the source for the measurements and variant specifications below.
How the three Breacher variants differ
| Variant | Function | Finish | Reported movement | Reported thickness | Launch-reported reserve | Announced launch price |
|---|---|---|---|---|---|---|
| Breacher time-only | Hours, minutes, seconds | Stainless steel | Sellita SW200-1 automatic | 11.2 mm | 38 hours | £1,399 |
| Breacher GMT | Time and second time zone | Stainless steel | Sellita SW330-2 automatic | 10.8 mm | 56 hours | £1,799 |
| Breacher Black Ops GMT | Time and second time zone | Black DLC-coated case | Sellita SW330-2 automatic | 10.8 mm | 56 hours | £1,999 |
All three prices are the figures announced at launch, not confirmed current prices. The launch report said the collection would be available from 6 March 2025; it does not establish present stock or sales status.

What the GMT adds
The stainless-steel and Black Ops GMT versions add a second-time-zone function. Time+Tide describes a fixed inner 24-hour ring for reading the GMT hand against. That differs from the time-only model, which displays hours, minutes, and seconds without a second-time-zone indication. The GMT is useful if you regularly track another time zone, but the fixed ring is not a rotating timing bezel.
Movements, reserve, and reported regulation
The time-only Breacher is reported to use the automatic Sellita SW200-1, with a 38-hour power reserve. Both GMT variants are reported to use the Sellita SW330-2, with a 56-hour reserve. Those reserve figures are the launch article’s specifications; they are not independent measurements.

The same launch report says Horologium regulates the movements to an average of +2/-3 seconds per day. This is a reported regulation figure, not an accuracy result from independent testing described here. If that level of precision is important to a purchase, confirm the current specification and warranty terms with the seller.

- Choose the time-only model if you want the simpler display and do not need to track another time zone. Its reported movement is the SW200-1 and its case is listed as 11.2 mm thick.
- Choose the stainless-steel GMT if the second-time-zone function matters and you prefer a steel finish. It uses the reported SW330-2 movement and is listed at 10.8 mm thick.
- Choose the Black Ops GMT if you want the GMT function in a black DLC-coated case. Its reported movement and thickness match the steel GMT; the launch price was higher.
Before buying, verify the exact variant’s current specification, price, stock, delivery region, warranty, and returns terms on the live product page. The launch figures alone cannot confirm those details.
