The U-Boat Darkmoon Black SS Ref. 9018/B delivers intense contrast and depth through oil immersion technology, presenting a deep black dial within a refined 42mm silhouette.

Engineered for visual clarity, this model is powered by a Swiss Ronda 712.3 quartz movement lubricated in oil, ensuring reliable performance while maximising dial legibility.

Finished with confident simplicity, the stainless steel case, curved sapphire crystal, and vulcanised rubber strap with quick-release system combine durability, comfort, and unmistakable U-Boat design.
