BLS produced: Jaeger-LeCoultre Polaris calendar watch, with a modern double handle design, and elegant and sporty fluent lines. Deep and elegant, yet extraordinary. [Case] ​​The watch size is 42X13.1mm. The classic and capable case is hand-polished, with brushed sides and polished edges. The craftsmanship and process are consistent with the original. The bottom cover is also engraved with Jaeger-LeCoultre-style diving clothing and engraved patterns. [Movement] The thin and stable 9015 movement is modified into the JCL.899A/1 movement. Thickness and function are both correct, perfectly restoring the authentic experience. [Strap buckle] The natural rubber strap is thin, long and soft, enough to wrap around the wrist, with the original Jaeger-LeCoultre buckle.
