Overlord model is more expensive than Polaris model.
Polaris is a self-produced movement, and Polaris is the only brand of domestic large watches with a self-produced movement, which is also a sigh of relief for domestic products;
Wang Ba used a German Hermle movement, and there is a jargon in the watch industry: "Swiss watch, German clock". Hermle and Kenninga are famous German brands, which are equivalent to "Mercedes-Benz" and "BMW" in watch movements.
Polaris and overlord are both big brands with guaranteed quality. Personally, I recommend Wang Ba MG2348BP, which is more athletic.
In addition, consider whether there are any dealers of Polaris or Overlord in your city. I suggest you choose your city. Otherwise, there is a certain probability that the floor clock will be damaged in long-distance transportation, and there is no guidance for the first debugging of the clock.
Also remind you:
Both clocks are chain-driven, and the winding process is complicated. I suggest you prepare yourself mentally.
If you have any questions, please ask. Note that I'm not a clock seller, I'm just a fan. )
