Strap for Universal Geneve Polerouter RU6910101B1X1

The lug width of the Polerouter RU6910101B1X1 is 19mm, measured from inner edge to inner edge between the case lugs. To verify the measurement correctly, use a calliper or millimetre ruler positioned perpendicular to the lugs, excluding any case decorations.

For the RU6910101B1X1 in rose gold, we recommend natural brown Mississippi alligator or vegetable-tanned calf leather: both ensure aesthetic elegance consistent with the watch's modernist design. Alligator develops authentic patina over time, whilst calf leather offers immediate comfort. NATO straps are a valid choice for those who wish to emphasise the functional and aviation heritage of the model.

To change the strap, place the watch on a flat surface. Locate the spring bars connecting the case lugs to the strap. Using a strap removal tool or small screwdriver, push the bar downward to release the old strap. Insert the new 19mm strap, aligning the holes with the bars, then release the spring bar. Verify the strap is firmly secured before wearing the watch.

Yes, all aftermarket straps measuring 19mm are compatible with the Polerouter RU6910101B1X1. We recommend choosing materials and finishes that respect the vintage aesthetic and heritage value of the timepiece, such as natural alligator, vegetable-tanned calf, or quality NATO fabric. Always verify the width is precisely 19mm before purchase.

The lifespan of a leather strap depends on material quality, frequency of use, and environmental conditions. High-quality alligator leather offers 3-5 years of moderate wear before replacement. Calf leather has similar longevity, whilst NATO fabric is more resistant to wear. Frequent exposure to moisture, direct sunlight, and temperature fluctuations shortens strap life. We recommend rotating between different straps periodically to distribute wear.
