Building upon the recently updated standard spec of the 6190, the M.S.L retains the same 37.7mm steel case. Thickness is 10.4mm, and the lug to lug is just 46.5mm. The lug width is 20mm, water resistance is 200 meters, the crown screws down, and the crystal is sapphire. Inside and supporting the time-only function set, we find a Swiss-made Soprod M100 automatic, which is COSC certified, has 42 hours of power reserve, and ticks at 4 Hz.Â
