The Heritage

The L & Jr Step One S1501 is a 45mm stainless steel chronograph watch with a 20mm lug width, featuring a Swiss Ronda 8040.N quartz movement. The brushed satin steel case houses functions including hours, minutes, small seconds, date window, and day indicator. The generous 45mm diameter ensures readability and presence, while the solid stainless steel construction develops a natural patina over time. The 20mm lug width parameter enables precise strap selection and compatibility with a wide range of aftermarket solutions.
