Frequently asked questions

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

The lug width of the SevenFriday M2/02GR is 28 millimetres. This measurement is critical for selecting compatible straps. To verify, measure the distance between the spring bar pins perpendicular to the strap using a digital calliper. Precision is essential, as even 1mm deviation compromises insertion and security.

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

The choice depends on intended use and aesthetic preference. For formal elegance, American alligator or vegetable-tanned calf leather offer patina development and character lines over time. For daily versatility, NATO textile straps create compelling visual contrast with the case's metallic geometry. FKM rubber remains ideal for sport and dynamic urban contexts, guaranteeing durability and moisture resistance.

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

Use a spring bar tool (specialised pin extractor). Position the micro-hook towards the inside of the lug, gently push until the pin disengages, and remove the old strap. Insert the new strap, aligning the hole, reinstate the spring bar by pushing until it clicks. Verify the pin is fully locked on both sides before wearing. Milano Straps straps are crafted with precisely calibrated lugs for optimal compatibility.

Can I use aftermarket compatible straps with the SevenFriday M2/02GR?

Absolutely. Certified quality aftermarket straps at 28mm fit the M2/02GR perfectly, without compromise. Milano Straps produces bespoke artisanal straps specifically calibrated for this lug width, featuring premium materials (alligator, calf, NATO, rubber) and custom finishes. Compatibility is guaranteed by standardised lug width specifications.

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

A quality leather strap (alligator, calf, shell cordovan) lasts 3-5 years with daily wear, potentially longer with proper maintenance. Vegetable-tanned leather ages better than chrome-tanned, developing distinctive patina. To extend lifespan, avoid prolonged water exposure, apply leather conditioner every 6-12 months, and rotate at least 2-3 straps in your collection. Milano Straps utilises certified leathers for maximum durability and longevity.
