I recently got a 'Strap Culture' strap.......this one
This strap is excellent quality, a real mans strap. Thick!! solid and with an excellent buckle. I hate the Panerai style buckle and there are not that many 24mm straps around without it. This one came with a right heft of a buckle that compliments the strap wonderfully, and with an excellent shape too.
One thing worth noting is size, i have an 8" wrist and this strap fits perfectly on the very last hole. Any one with a bigger wrist will need a longer strap or a leather hole punch.
My LM1-LE is now looking perfect. Get one of these straps, they are superb.
