Important Notes
The MS-8657 comes complete with the watch, an original packaging box, a strap removal tool, an English manual, and a fiber cloth for cleaning. All measurements are manually taken; slight variations may occur (size ±1mm, weight ±2g). To preserve accuracy and longevity, avoid adjusting the time or date between 9:00 PM and 3:00 AM, when internal mechanisms are most active. Always wind the crown clockwise and ensure it is fully locked after adjustments to maintain water resistance. Manual winding is recommended if the watch has stopped, and users should verify calendar function by testing the date jump at 12 o’clock. Proper care includes avoiding sudden impacts, extreme temperatures, and prolonged exposure to chemicals.
