In my opinion, the tissot seastar 1000 is the best dive/daily watch under 800 dollars as it features sapphire crystal, ceramic bezel, see-through caseback, 300 meter water resistance, and the well known powematic 80 caliber (eta 2824-2 with 80 hour power reserve) presumably being able to achieve near-cosc accuracy and an available with a silicone (for magnetic fields resistance) hair spring. If someone knows a watch with a better bang for buck please name it. (Hope this post doesn’t make the watch’s price to go up)
