D1 Milano Ultra Thin watches measure just 6mm to 7mm thick, sitting flat against the wrist and sliding easily under a cuff. The collection spans men's and women's designs in case sizes from 30mm to 40mm, each protected by scratch-resistant sapphire crystal.
Powered by low-profile Citizen Miyota quartz movements and available on integrated steel bracelets or leather straps. Explore the full range below.
The defining specification of the Ultra Thin collection is a case thickness of 6mm to 7mm. That is slim enough to disappear under a shirt cuff entirely and to add almost no bulk on the wrist. It is achieved through a low-profile movement and careful case engineering rather than by shrinking the watch overall.
Sizes for Every Wrist
The collection is divided across multiple diameters, from delicate 30mm cases through mid-size options up to 40mm. Smaller sizes read as refined and dressy while larger cases give a bolder contemporary presence. Because the case stays thin throughout, comfort holds across the range.
Sapphire Crystal Throughout
Every timepiece in the Ultra Thin collection is fitted with premium sapphire crystal engineered with an anti-reflective coating. Sapphire resists the scratching a slim everyday watch is exposed to, and the coating keeps the dial readable in varied light.
Low-Profile Quartz Movement
These watches are powered by highly reliable, low-profile Japanese quartz movements from Citizen Miyota. That choice is what makes the 6mm to 7mm case possible: a mechanical movement would require significantly more depth.
Bracelets and Straps
Depending on the model, the Ultra Thin line offers a seamlessly integrated 316L stainless steel bracelet or a leather strap, across silver, gold, and rose gold finishes. Bracelet links are removable so the fit can be tailored.
