Of course, the main talking point here is the YEMA3000 calibre at the heart of this piece. The in-house movement has made appearances in the Worldtimer and Hertiage GMT collections previously and allows the wearer—in conjunction with the 24-hour bezel insert—to track a total of three time zones. However, this caller-GMT has never been used in a 50BAR watch before. In fact, this combination of water resistance and GMT function place the Superman 500 GMT among small school of fish.
The PVD-coated tonneau-shaped CHR comes in with a case diameter of 41.5mm, a lug-to-lug distance of 47mm, a thickness of 10.9mm and a lug width of 22mm. As you can see from the photos below, it fits nicely on my 6.25” (16cm) wrist due to having a short lug-to-lug distance and thin profile. The tonneau case definitely helps make the watch look and feel great on the wrist, and having a mecaquartz movement within, you are looking at a lightweight timepiece.
The Seastar name first appeared in the Tissot catalogue in 1954, but not as a dive watch, or a chronograph. It was in reference to its caseback, which used new technology to repel moisture and dust. The latest iterations certainly do that. True to its name, the Seastar 1000 offers up a whopping 300m (1000ft) of water resistance, due in part to its screw down crown and caseback. To achieve this in the chronograph version, the brand has also designed funky, screw down pushers.
