Club 703.S4— lug 18mm

The Nomos Glashütte Club 703.S4 features a lug width of 18 millimetres. This dimension was carefully calculated to visually balance the 36 mm case with the case lugs themselves. When measuring your strap, always measure the internal distance between the lugs: measuring from the outside will result in an incorrect order.

We recommend alligator leather with vegetable tanning or calf leather for the Club 703.S4: both reflect the rational construction philosophy of the watch. Alligator develops a natural patina that increases its character over time. Alternatively, a NATO in navy blue or black, or a rubber strap in charcoal grey, offer versatility without compromising the watch's aesthetic.

The Club 703.S4 features straight lugs integrated into the case. To replace the strap, use a spring bar tool to gently extract the spring bar from one side. Once both springs are removed, slide the old strap away and insert the new one horizontally into the lugs. Reinsert the springs with even pressure until you feel the locking click.

Yes, provided the lug width is exactly 18 millimetres. Artisanal straps produced by specialist ateliers such as Casati Milano are fully compatible with the Club 703.S4. Always verify the technical specifications from the vendor before ordering and request samples if necessary.

The lifespan of a leather strap depends on usage intensity, climate and tanning quality. An alligator or vegetable-tanned calf strap, worn daily, typically lasts 3-5 years. Rubber tends to last longer, 5-7 years. The natural patina of the leather ages pleasantly, adding character to the strap over time.
