The Heritage

The SevenFriday M-Series M2/02 features a 47mm stainless steel case with automatic movement and a distinctive layered dial that exposes its structural components. The lug width is precisely 28mm, an unconventional dimension reflecting the watch's bold proportions and contemporary design philosophy. The case material is robust stainless steel, designed to develop natural patina over time, while the stratified dial creates optical depth and dynamic light interaction.

FAQ

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

The lug width of the SevenFriday M2/02 is 28mm. This is a non-standard measurement, incompatible with universal 20mm or 26mm straps. It is essential to verify compatibility before purchasing aftermarket straps.

What is the best strap for the SevenFriday M2/02?

The best strap depends on personal use and style. Alligator leather with fine grain adds elegance whilst maintaining material severity. Calf leather with vegetable tanning offers natural patina development over time. A cotton-nylon NATO ensures daily versatility and robustness. Technical FKM rubber preserves contemporary aesthetics for active contexts.

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

The M2/02 uses standard spring bars. Obtain a spring bar removal tool. Insert the blade into the lateral slot of the lug to compress the pin, then extract the old strap. Insert the new strap, aligning it with the attachments, press gently until the securing click. Verify that the pin is fully locked before wearing the watch.

Can I use a quality aftermarket strap on a SevenFriday M2/02?

Yes, provided it is certified for 28mm lug width. We recommend specialised suppliers that guarantee precise tolerances on this non-standard measurement. Quality aftermarket straps often offer greater customisation than original straps, both in material and finish.

How long does a leather strap last on a SevenFriday M2/02?

Durability depends on the type of tanning and usage. Alligator or calf leather with vegetable tanning lasts 4–7 years with moderate daily use. Cleaning frequency, humidity exposure and perspiration determine ageing. Regular maintenance (neutral detergents, air drying) significantly extends strap lifespan.
