The Martin-Baker MBIIAn, seen from the bench

The Bremont Martin-Baker MB II Anthracite is a 43mm stainless steel instrument watch developed with Martin-Baker, the British ejection seat manufacturer. It features the Bremont caliber BE-36AE automatic COSC-certified chronometer movement with hours, minutes, seconds, date function and day indication. The 22mm lug width is engineered for optimal structural support and ergonomic compatibility, calibrated through years of military pilot testing.

Frequently asked questions

What is the lug width of the Bremont Martin-Baker MBIIAn?

The lug width of the Bremont Martin-Baker MBIIAn is 22 millimetres. This dimension is specific to the model and is not interchangeable with 20mm or 24mm lugs. To verify compatibility, measure the distance between the lug shoulders on the underside of the case: it must be exactly 22mm.

What is the best strap for the Bremont Martin-Baker MBIIAn?

The choice of strap depends on intended use. For everyday wear and tactical versatility, a NATO Premium in black, military grey, or sand is the ideal choice. For a more refined approach, vegetable-tanned leather in Tuscan brown or olive-drab tonalities enhances the aviation watch aesthetic without compromising functionality. Vintage alligator offers a luxury solution consistent with the instrument's spirit.

How do you change the strap on a Bremont Martin-Baker MBIIAn?

The strap is changed by removing the lug pins (spring bars) using a dedicated tool or watchmaker's needle. Position the watch on a stable surface and, with care, compress the internal spring of the pin whilst extracting it from its seat. Once the old strap is removed, insert the new one by aligning the lugs with the holes and reinsert the pin. No watchmaker visit is necessary: any enthusiast can complete this operation in 30 seconds.

Are aftermarket straps compatible with the Bremont Martin-Baker MBIIAn?

Yes, all standard straps with a 22mm lug width are compatible with the MBIIAn. Milanostraps offers a complete range of certified straps in leather, NATO, and rubber specifically dimensioned for this size. Compatibility is guaranteed: each strap is engineered to fit the case lugs perfectly.

How long does a leather strap last on the Bremont Martin-Baker MBIIAn?

A quality leather strap, such as vegetable-tanned Tuscan leather, has an average lifespan of 3–5 years with daily wear, provided proper maintenance is observed. The ageing of leather is predictable and desirable: the patina that develops amplifies the watch's character. An alligator strap, owing to the greater density of the skin, can last 5–8 years. NATO straps, being synthetic textile, have a similar lifespan but require less maintenance.
