As long as it is sold by Amazon, it should be reliable. The specific reason for the cheapness is two reasons:

1. You need to see clearly whether it is brand new. Some watches are second-hand and the price will be cheaper.

2. Tariffs are indeed an important factor affecting prices. Secondly, the pricing of the same brand will be different in different regions. To give an example of what I bought a few days ago, I bought a Citizen XC series watch in Japan. Counting the store discount, tax refund and UnionPay card discount, it is definitely thousands cheaper than the Citizen XC watch in China. As for pricing, I don’t know about other things. For Citizen, the same model EC1110-52A watch sells for 73,000 yen (equivalent to RMB 4,470) in Japan and HKD 6,100 (equivalent to RMB 5,284) in Hong Kong. As for the domestic market price, I won’t say much. After saying so much, you should understand what I mean.
