What we do best
From rugged dive watches to elegant dress pieces, modern watch models each have a distinct personality that makes them beautiful in their own way. Dive watches stand out with bold bezels, luminous markers, and confident proportions that feel powerful and adventurous, while GMT models add depth and complexity with extra hands and layered dials that speak to travel and precision. Dress watches embrace simplicity and balance, using clean lines, refined cases, and subtle details to create timeless elegance. Field and everyday sport models blend practicality with style, offering versatile designs that feel effortless on the wrist. Seiko mods bring all of these models to life by combining proven Seiko reliability with carefully chosen custom components, turning each watch into a unique expression of craftsmanship, detail, and personal style.

At Caes Custom Watches, we elevate classic Japanese design with the precision and prestige of Swiss-made movements. Each watch is powered by premium calibers—such as the NH35 or NH34—renowned for their accuracy, durability, and refined engineering. These self-winding mechanical movements, beating at 28,800 vibrations per hour, bring smooth performance and enhanced reliability to every build. Carefully regulated and integrated in-house, they reflect a seamless blend of rugged Seiko heritage and the timeless craftsmanship of Swiss horology—delivering a timepiece that’s as precise as it is distinctive.
