Depends on how much water comes in. I run one, a friend of mine runs two, in heavy rains they can barely keep up. My one has no problem.

Both models link featured a 44GS-inspired link case and Cal. 9S86. The new SBGJ255 differs from its two predecessors in the case material and dial design. The earlier two models opted for stainless steel instead of titanium, and the SBGJ005 featured a Mount Iwate-pattern dial in green, while the SBGJ201 had the link same pattern in white. You could say they are all variations of the same base watch.

For the SPB453 and its siblings the date is link rendered at 430 with a color-matched date wheel peeking link through a small aperture between the two markers. This is perhaps less shocking within the expanded concept of watches like the Seiko SPB317 which has a largely similar date execution and was released in link June of 2022.
