The CLEAN Factory Submariner CM3 Upgrade Edition is a refined interpretation of the classic 40mm diver-style watch, designed to emphasize improved dial clarity, enhanced material consistency, and upgraded mechanical stability. Built for enthusiasts who value detailed finishing and balanced proportions, this model focuses on delivering a more cohesive and visually accurate wrist presence.
The watch features a 40mm case constructed from 904L stainless steel, known for its high corrosion resistance, durability, and refined polishing characteristics. Paired with a matching steel bracelet, the overall structure delivers a solid and premium feel while maintaining the classic Oyster-style diver silhouette.
Inside, the watch is powered by a Dandong 3135-style automatic movement, designed for stable performance and reliable timekeeping in daily wear conditions. The movement architecture emphasizes smooth operation and improved durability, supporting consistent functionality across extended use.
One of the key highlights of this edition is the upgraded dial design. The dial adopts a clean, balanced layout with improved print clarity and refined hour marker execution. The visual consistency between the dial markers and luminous application has been carefully optimized to create a uniform glow effect in low-light conditions.
The ceramic bezel insert is developed with an upgraded color tone closer to the original aesthetic reference. It offers improved scratch resistance and a smoother surface finish, while maintaining strong legibility of the diving scale. The luminous pearl at the 12 o’clock position is designed with a softer tone for better visual integration with the bezel.
Additional refinements include improved date wheel alignment and font consistency, as well as enhanced hand finishing with better edge polishing and luminous filling. These details contribute to a more unified and polished overall appearance.
The bracelet is constructed from 904L steel with alternating brushed and polished surfaces, ensuring both comfort and visual depth. The clasp system provides secure locking with engraved detailing for added refinement.
The CLEAN Factory CM3 Submariner Upgrade Edition is designed for enthusiasts who appreciate modern refinements of a classic diver design, combining durable materials, improved visual consistency, and stable mechanical performance in a versatile everyday watch.
