Explorer II 16570-0002— lug 20mm

The lug width of the Explorer II 16570-0002 is precisely 20mm. This measurement is specific to this generation of the timepiece and represents the distance between the inner lugs of the case where the strap attaches. Verifying this dimension before purchasing an aftermarket strap is essential, as an incorrect width would compromise both the aesthetics and functionality of the watch.

For the Explorer II 16570-0002, high-grade alligator leather with vegetable tanning offers the best balance between elegance and technical resilience, particularly considering the watch's polar heritage. Shell cordovan, however, develops an enviable natural patina over time, whilst an FKM rubber strap on an integrated deployante represents the most rigorous choice for extreme environments. Selection depends on primary use: formal/daily wear (alligator or calf), aesthetic distinction (shell cordovan), or genuine expeditions (sports rubber).

Changing the strap on an Explorer II 16570-0002 requires a specific tool: a spring bar tool or fine tweezers. Gentle pressure must be applied to one of the lateral elastic pins to release the strap from the case. Although technically straightforward, professional execution by a qualified watchmaker is recommended to prevent damage to the case or pins. Milano Straps provides straps with pins already installed and ready for immediate use.

An aftermarket strap is entirely compatible with the Explorer II 16570-0002 provided it features a 20mm lug width and is designed for standard spring bar attachment. Artisanal natural leather straps from Milano Straps, custom-made to this specification, are completely compatible and guarantee superior quality compared to OEM alternatives. It is crucial to verify that the lugs possess correct thickness to prevent play or stress on the case.

A high-quality natural leather strap, subject to ordinary maintenance, typically lasts 3-5 years on a daily-worn timepiece. Longevity varies considerably depending on material: alligator and shell cordovan with vegetable tanning tend to outlast calf leather, developing a patina that enhances character. Exposure to perspiration, humidity, and UV radiation accelerates ageing. Milano Straps offers an 18-month warranty against manufacturing defects and recommends periodic maintenance with natural oils and balms to preserve leather integrity.
