Haylou has announced the RS4, another affordable smartwatch by the company. The RS4 features a 1.78-inch AMOLED display, a GPS module and is IP68 certified. The 45 mm smartwatch should last up to 25 days on a single charge of its battery, too.

I can't see GPS module on Haylou site specs. May be you wrong..?
Not swimming proof like the rs3 and also not listed with gps.
While I am not super satisfied with the rs3 it still a good watch with gps and adequate measurements for swimming. This new one is for the show only.
