Strap for Club Aqua Automat Datum

The lug width of the Club 775 is 20mm. This measurement is standard for this 41.50mm case diameter and ensures harmonious proportions between the watch body and strap. To verify your watch's lug width, measure the internal distance between the two case lugs using a digital calliper.

The 775 pairs perfectly with vegetable-tanned leather (alligator or calf) in cognac brown or powder grey tones, which respect the watch's austere aesthetic. Alternatively, a cotton NATO in neutral colours maintains everyday wearability, whilst FKM rubber offers contemporary practicality. Your choice depends on intended use: formal occasions call for leather, casual wear suits NATO or rubber.

The Club 775, like all watches, uses spring bars to attach the strap to the case lugs. Using a spring bar removal tool, push the pin upward from beneath to release the previous strap end. Insert the new 20mm strap, align the hole with the pin, and allow the pin to snap naturally into place. If you lack experience, consult a qualified watchmaker.

Yes, any strap with a 20mm lug width is compatible with the Club 775. However, we recommend selecting materials and finishes (vegetable-tanned leather, cotton NATO, minimalist rubber) that reflect Glashütte's constructive philosophy: the 775 communicates best with honest, understated materials that age gracefully rather than deteriorate.

A high-quality vegetable-tanned leather strap, with ordinary maintenance, typically lasts 3-5 years before requiring replacement. Durability depends on frequency of wear, moisture exposure, and care practices: avoid prolonged immersion, dry promptly after perspiration, and occasionally apply vegetable wax to maintain flexibility. Vegetable-tanned leather's advantage is its visible ageing, generating personal patina.
