01 / The design
The design, in detail
The Rolex Datejust debuted in 1945, making the date display a defining feature of a versatile everyday watch. Its lasting appeal lies in the balance of calendar function and polished proportions. Roman numerals bring a more formal, architectural rhythm to the dial. For Roman Tiffany Blue, USAMODWATCH brings those historical design cues into an independently assembled custom edition.

02 / The color
Color, held in contrast
Between blue and green, turquoise brings a fresh, unmistakable mood to the dial. Roman numerals bring a more formal, architectural rhythm to the dial. In Roman Tiffany Blue, that relationship is the center of the design.
04 / The movement
The NH35
Automatic
The NH35 is a 24-jewel automatic movement running at 21,600 vibrations per hour. Wrist motion winds the mainspring, while manual winding and hacking seconds make setting the watch straightforward. Its mechanical architecture gives this custom build a traditional self-winding foundation.

“The watch is beautiful, and my wife absolutely loved it. The only issue I have is with the presidential wristband I ordered with it — once it’s on, it’s almost impossible to open because the clasp is extremely stiff.”
