Ball Watch
Engineer Hydrocarbon DC3026A-SCJ-BK— lug 22mm

The lug width of the Ball Watch Engineer Hydrocarbon DC3026A-SCJ-BK is 22 millimetres. This measurement is taken from the centre of the front lug pin to the centre of the rear lug pin. A compatible strap must have an internal width of exactly 22 millimetres to ensure a precise fit without lateral play.

For the DC3026A-SCJ-BK, alligator leather straps with vegetable tanning are recommended for formal use and long-term durability, or NATO straps in canvas for sports and operational contexts. Your choice depends on intended use: if you frequent diving or humid environments, vulcanised rubber is the most reliable technical solution.

Strap replacement is performed using a spring bar tool: position the forked tip under the front lug pin, gently pull downward until the internal spring compresses, then slide the pin out of the lug. Repeat this procedure on the rear pin. Reverse the process to install the new strap, ensuring both pins are fully seated and the springs click into position.

Yes, any strap with a 22-millimetre lug width is compatible. However, we recommend verifying the centre-pin measurement: some manufacturers measure from the outer edge of the lug, producing inaccurate results. Artisanal-quality straps guarantee precise tolerances and secure fitment.

A quality alligator or calf leather strap with vegetable tanning lasts an average of 3–5 years with daily use if properly maintained (wiping with a dry cloth, annual conditioning with neutral balm). Exposure to constant humidity, chlorine and sea salt reduces longevity to 1–2 years. Canvas NATO straps last 5–7 years; vulcanised rubber can exceed 10 years whilst maintaining excellent flexibility.
