This watch reflects years of dedication, perseverance, and passion.

It carries Machiel Hulsman's signature case shape with open lugs.
It has an in-house movement made from traditional materials.
The perpetual calendar is Machiel Hulsman's proudest achievement.

After months of design and calculation, Machiel Hulsman is ready to build it with you.

• The date hand jumps over the two prisms at 2 and 4 o’clock to keep them visible.

• On the back, you see the day and month display, plus the leap year indicator.

• No pushers or correctors are needed.

Dial Features

• Winding indicator on the left, reminding you when to wind.

• Over 90 hours of power reserve means you won’t wind it often.
