At the heart of the Dumas lies the reliable Japan NH35 TMI Automatic movement, renowned for its durability and precision. This self-winding mechanism ensures that the watch keeps time accurately, powered by the motion of the wearer's wrist, eliminating the need for daily winding.

The case is crafted from high-grade stainless steel, measuring 44mm in diameter and 15mm in thickness. This substantial size underscores the watch's bold presence, while the sapphire lens atop the dial, complete with an anti-reflective coating, guarantees clarity and scratch resistance under a variety of conditions.

A key feature of the Dumas is its unidirectional turning bezel with glass, a nod to the watch's diving watch heritage. This functional element not only adds to the watch's sporty aesthetic but also serves as a practical tool for tracking diving times or other time-measured activities.

The watch is fitted with a 22mm stainless steel bracelet, featuring a fold-over buckle with a safety lock to ensure a secure fit during any adventure, whether underwater or on land. The lug-to-lug measurement of 48mm contributes to the watch's comfortable fit, making it suitable for a wide range of wrist sizes.

Designed to withstand the pressures of deep-water exploration, the Dumas boasts an impressive water resistance of 300 meters. This capability makes it an ideal companion for professional divers and aquatic sports enthusiasts alike, offering reliability and resilience in challenging environments.

Each Spinnaker Dumas Soda Blue Automatic Watch comes with a 2-year international warranty, offering peace of mind and assurance in the quality and durability of this exceptional timepiece.

The SP-5081-JJ is not just a watch; it's a tribute to the daring design and engineering feats of the past, updated for today's discerning collector. With its striking appearance, mechanical reliability, and practical features, the Dumas Soda Blue is a standout model that offers both style and substance for watch enthusiasts and diving aficionados.
