Its £2,500 listed sale price puts the buying decision on the case variant and design as much as on the movement: the Aqua Blue edition uses forged carbon, while the Navy Blue/Flame Orange edition uses titanium. Bamford’s product pages displayed that sale price when accessed in 2026; it may change.
How the B347’s monopusher chronograph works
Unlike a conventional chronograph with separate start/stop and reset pushers, the B347 uses one push-button at 2 o’clock. Bamford describes the movement as cam-operated: successive presses start, stop and reset the chronograph. The display has a central 60-second counter and a 30-minute counter at 3 o’clock; the date appears at 6 o’clock. This is a single-button control arrangement, not a claim that every function of the watch is operated by that button.
The movement is the Sellita SW510 MPa. Bamford lists 28,800 beats per hour (4 Hz), 27 jewels and a 62-hour power reserve. Those figures are manufacturer specifications, not independent measurements of this particular watch.

Dimensions and specifications in the table are from the respective Bamford product pages, accessed in 2026. The 48.5 mm lug-to-lug measurement is stated for the titanium page only; it should not be assumed for the carbon model. Price is a time-sensitive manufacturer listing, not a promise of current stock, availability in every region or third-party pricing.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Choosing between the cases
The material and color scheme are the clearest documented differences. Worn & Wound describes the carbon version as noticeably lighter than the titanium version, a favorable impression in its review. That is a qualitative reviewer observation, not a controlled weight comparison or a published mass measurement. The available specifications do not establish a numerical weight difference.
What the official specifications do—and do not—tell you
Bamford lists 100 m / 10 ATM water resistance for both cited editions. That rating is a manufacturer specification; the product-page figures alone do not establish the condition of an individual watch or its suitability for a particular activity. The carbon page also specifies a black-coated steel caseback.

The published 62-hour reserve indicates the duration Bamford specifies when the movement is fully wound, but does not establish how accurately a given example keeps time. The sources cited here provide no independent accuracy measurement, service-cost evidence or hands-on test. Warranty terms, current stock and availability by geography are likewise not established by these product listings.
Price and value at the listed level
Bamford’s carbon and titanium pages each displayed a £2,500 sale price when accessed in 2026. Because these were marked sale prices, treat them as snapshots rather than a stable recommended retail price. Check the live listing, final checkout amount, shipping and applicable taxes before deciding; the cited pages do not establish third-party prices.

At that listed price, the B347’s case treatment, colorway and one-button chronograph are central to its appeal. The supplied specifications identify a Sellita movement and useful everyday dimensions, but they do not provide independent timing results, measured weight, or comparative service costs. A buyer who prioritizes verified accuracy or long-term ownership costs would need evidence beyond the claims and impressions available here.

Michelin announced a MICHELIN x Bamford B347 Pilot Sport collaboration with a 41.5 mm forged-carbon case and Sellita SW510 MPa movement. Michelin also describes a strap made using recycled Pilot Sport tyre material. That strap detail belongs to the named collaboration; it should not be assumed to apply to every B347 variant.
