I Would Like More Info on This Item

The unchanged case of the ATUM Pure L stands out with its slender bezel. The crown and pusher are telltale signs of the characteristic winding mechanism that also shines through the dial. A black alligator strap is combined with the polished stainless steel and stainless steel DLC dianoir cases. The contrast color of the carefully stitched seam matches the respective color of the HyCeram fillings in the dial.

Ref. MG-001088
