AQUASTAR Genève – Vintage Genuine Leather Watch Strap – 18 mm – Swiss Made
Overview
Aquastar was a Swiss watch brand established in Geneva in 1962, originally specializing in professional dive watches. This strap is an original OEM leather strap designed for vintage Aquastar models, crafted in Switzerland from genuine leather. The strap is finished in black with matching black stitching, maintaining the utilitarian aesthetic of Aquastar’s tool watches from the 1960s and 1970s.
The strap measures 18 mm at the lugs and tapers to 16 mm at the buckle, following the proportions typical of mid-century dive watch straps. The short end measures approximately 75 mm, while the long end is approximately 115 mm, providing a standard fit for most wrist sizes. The strap is marked with the original Aquastar branding: AQUASTAR GENEVE | GENUINE LEATHER | SWISS MADE, confirming its authenticity and provenance. Condition is graded Excellent in our Condition Grading Scale below, with no visible wear beyond minor surface patina consistent with age.
Included with the strap is the original unmarked Aquastar buckle, a period-correct tang buckle in stainless steel. This strap is suitable for collectors restoring vintage Aquastar models or for those seeking an authentic Swiss-made leather strap for compatible 18 mm lug watches. The strap is sold as a complete set with the buckle, with no additional links, spring bars, or packaging included.

Compatibility
This strap is designed for Aquastar watches with 18 mm lug widths, including models such as the Aquastar Benthos 50, Benthos 100, and Regate. It will also fit other vintage or modern watches with 18 mm lug spacing, though the taper to 16 mm at the buckle should be confirmed for compatibility. The included buckle is a standard tang type, requiring a strap with a 16 mm end width. For watches with fixed spring bars (e.g., some one-piece cases), ensure the spring bars can be removed to fit this strap.
