Unimatic has introduced two new additions to its ProDiver collection, building on the initial ProDiver release from 2025. After the first 300-piece run sold through, the brand now returns with updated black (U1S-PD6-B) and royal blue (U1S-PD6-RB) references that keep the design intact while improving the overall configuration.
The case remains 40mm in stainless steel, measuring 41.5mm when including the bezel overhang. The vertically brushed finishing and restrained case architecture stay true to the industrial language Unimatic has leaned on since its earliest releases. Nothing about this design feels ornamental, which continues to be part of its appeal.
The dial layout is unchanged. Matte black or royal blue serve as the base for the triangle-dot-dash hour markers, with a date window at six using a color-matched disc to maintain balance. A ceramic bezel insert adds scratch resistance without altering the minimalist presentation.
The phantom handset returns here as well. Because the hand frames blend into the dial color, the luminous sections stand out more clearly in low light. Blue Super-LumiNova is used for the minute hand and five-minute bezel markers, while the hour hand, seconds hand, and indices glow orange. The separation is practical, making elapsed time easier to distinguish at a glance.
The most significant update is the 600-meter water resistance rating. That matches the earlier titanium flagship and doubles the depth rating of the original steel version. On paper, that shift matters. It moves the watch beyond aesthetic dive cues and aligns it with the technical expectations of a serious tool watch.
Inside, both models use the Sellita SW200-1 automatic movement, operating at 4Hz with a 41-hour power reserve. It is a common, serviceable caliber, and in a watch positioned around durability and function, that familiarity makes sense.
The most notable refinement to me is the bracelet. This version arrives on a three-link stainless steel bracelet finished to match the case. The folding clasp integrates a diver extension that adds 15.6mm and doubles as a tool-less micro-adjustment system in 2.5mm increments. Compared to the earlier steel configuration, this setup feels more complete out of the box. A color-matched rubber strap is also included.
Each reference is limited to 300 pieces and priced at $1,960. Relative to the earlier titanium model that was delivered on a NATO strap at a similar price point, this steel configuration presents a more integrated package.
From my perspective, this release reads as refinement rather than reinvention. The design language remains consistent, but the increased depth rating and upgraded bracelet address the areas that previously felt transitional. For collectors who prefer Unimatic when it leans into its core tool-watch identity, this iteration feels like a slam dunk.
