Club 703— lug 18mm

The lug width of the Club 703 is 18mm. This measurement is taken from the inner side of the case, between the two strap attachment pins. It is specific to this model and does not conform to modern standard widths of 20mm or 22mm, requiring custom-made straps.

Mississippi alligator represents the luxury choice: the regular scale texture enhances luminosity and complements the minimalist case. Vegetable-tanned calf leather is ideal for those seeking a patina that evolves over time. Nylon NATO offers a sportier alternative, while fluoroelastomer rubber is recommended for water use or humid environments.

Use a dedicated pin remover tool or a small hammer and punch. Place the watch on a soft surface to prevent scratches. Gently press the pin from the inner side of the case outward, then remove the old strap. Align the new strap with the holes and reinsert the pins from the outside inward, ensuring they are fully locked.

Yes, but with precision required. Verify that the width is exactly 18mm, measured from the outer edge of each side. The strap thickness should ideally not exceed 1.6mm to maintain the proportions of the slim case. European artisanal straps are the most reliable choice for measurement accuracy and construction quality.

A quality leather strap—alligator, vegetable-tanned calf, or box calf—lasts 3-5 years with daily use and regular maintenance. Longevity depends on exposure to water, direct sunlight, and environmental humidity. A vegetable-tanned strap ages and develops patina, remaining functional beyond 5 years. Maintenance: periodic cleaning with a damp cloth and conditioning with natural wax significantly extends service life.
