FAQ

What is the lug width of the SevenFriday M-Series M2/02AB?

The lug width of the SevenFriday M2/02AB is 28mm. This measurement is determined by the distance between the two lugs on the case where the strap is attached. It is a relatively wide dimension, consistent with the substantial proportions of the 47mm case, and provides access to a broad range of compatible artisanal and industrial straps.

Which strap is best for the SevenFriday M2/02AB?

Strap selection depends on intended use and personal preference. For those who appreciate aesthetic contrast, an alligator leather strap with vegetable tanning emphasises sophistication whilst maintaining the case's brutal character. For a more industrial aesthetic, choose a NATO in Cordura or a technical rubber strap. Vegetable-tanned calf leather offers an ideal compromise between artisanal authenticity and price accessibility.

How do you change the strap on a SevenFriday M2/02AB?

To change the strap, use a spring bar removal tool positioned perpendicularly to the spring bar. Apply gentle inward pressure to retract the pin and pull the strap outward. Repeat on the second end. This operation requires care to avoid scratching the case; if inexperienced, consult a qualified watchmaker.

Are aftermarket straps truly compatible with the M2/02AB?

Yes, provided they strictly respect the 28mm lug width specification. Always verify the technical specifications of the strap before purchase. Quality artisanal straps, crafted from premium leathers or technical fabrics, are not only compatible but often enhance the aesthetic and tactile experience of the watch compared to the original strap.

What is the lifespan of a leather strap for the SevenFriday M2/02AB?

A quality leather strap with vegetable tanning, subject to regular use and appropriate maintenance (occasional cleaning, protection from excessive moisture), has an average lifespan of 3–5 years before replacement is required. Natural leather develops patina and oxidises over time; this process is desirable and contributes to the object's character. With careful stewardship, some vegetable-tanned straps achieve 7–8 years of service life.
