I believe my personal Leman was produced in the early 2000s, which would be a later production model, but I acquired mine late last year on the secondary market, fresh from a Blancpain service, where a silicon balance spring was added to the movement. I've considered hunting down an OEM Blancpain X71 bracelet to https://www.diybricksx.com/product-category/x-series/ pair with it, but I generally prefer leather straps and have been quite happy https://www.diybricksx.com/product-category/steampunk-minifigure/ with the burgundy Hodinkee Sedona calfskin strap it's pictured on https://www.diybricksx.com/product-category/cyberpunk/ in this story.
