Strap for Engineer II Chronometer Red Label

The lug width of the Ball Watch Engineer II NM2026C-LCJ-BK is 20mm. This measurement should be verified internally between the two horizontal attachment points of the case to ensure compatibility with aftermarket straps. A 20mm lug width is the intermediate standard for medium wrist circumferences and 40mm cases.

For the Ball Engineer II NM2026C-LCJ-BK, we recommend straps in vegetable-tanned leather (calf or alligator) for elegant daily wear, or rubber FKM or synthetic NATO straps for high humidity conditions. The ideal colour is black, dark brown, or navy blue to maintain visual unity with the black matte dial and luminescent indices.

The lug attachments are typically fitted with internal spring bars. To remove the strap, use a dedicated spring bar tool to push the spring inward and release the pin. Repeat on both sides. To install the new strap, insert the pin into the compressed spring and release gently. Always verify that the strap is secure before wearing the watch.

All straps with a 20mm lug width are compatible with the Ball Engineer II NM2026C-LCJ-BK. Always check the manufacturer's technical specifications before purchase. On milanostraps.it you will find straps in leather, NATO, rubber and shell cordovan, all available in 20mm size and ready for dispatch with personalisation options.

A high-quality leather strap with vegetable tanning lasts an average of 18-36 months under daily and moderate use. Durability depends on exposure to moisture, frequency of wear and maintenance care. Vegetable-tanned leather straps develop patina over time, improving visually. Avoid prolonged exposure to fresh or salt water, which accelerates ageing. Rubber and synthetic NATO offer greater longevity in extreme environments.
