Strap for Polaris Automatic Date Stainless Steel / Black / Rubber

The Jaeger-LeCoultre Polaris 9068671 features a lug width of 21mm, determined by the distance between the two spring bar holes on the case. To verify compatibility, measure the gap between the lugs with a calliper or ruler — even half a millimetre discrepancy can affect the fit. All straps in the MilanoStraps 21mm collection are certified to this exact specification.

The Polaris 9068671 pairs excellently with four strap types. Alligator leather offers geometric texture that echoes the brushed dial — choose cognac brown or anthracite grey for elegant contrast. Shell cordovan (leather from the horse's back) suits those desiring a patina that improves with time. Vegetable-tanned calf is ideal for versatile daily wear across formal and casual contexts. Military-grade nylon NATO straps emphasise Jaeger-LeCoultre's 1970s sportwatch heritage. Casati Milano allows you to examine leather samples and choose with full confidence.

Strap replacement requires removal of the spring bars using a dedicated tool (spring bar tool). Place the watch on a soft surface (microfibre cloth), press the spring bar laterally to create clearance, extract with care and remove the old strap. Insert the new 21mm-certified strap, aligning the holes, and reinsert the spring bar until you feel the click — it must sit firmly but never be forced. If you lack confidence, consult a watchmaker. Casati Milano offers professional fitting in their Milan laboratories by appointment.

Absolutely. The Polaris 9068671 accepts any aftermarket strap with 21mm lug width, regardless of brand. MilanoStraps' handcrafted straps — produced in Italy using premium leathers such as alligator, shell cordovan and vegetable-tanned calf — deliver superior construction quality compared to industrial alternatives. Casati Milano also produces bespoke straps: select the leather, colour, buckle style and stitching technique, receiving a strap conceived specifically for your Polaris.

A high-quality natural leather strap typically lasts between 4 and 8 years depending on daily use and humidity exposure. Casati Milano straps, handmade with premium vegetable-tanned leathers, benefit from robust construction extending longevity. The natural patina they develop (especially in shell cordovan and vegetable-tanned calf) adds visual character rather than diminishing appearance. Casati Milano provides 18 months' warranty against manufacturing defects and recommends occasional maintenance: keep the strap dry, apply natural balms once yearly, and in intense summer months, alternate with a NATO strap to reduce perspiration exposure.
