Made by APS factory, this replica Rolex Daytona has a weight of 146.8 grams, which is very close to genuine watch. Now only two factories are making Daytona replicas with increased weight, one is APS, the other is Gold, I recommend Gold, but it seems like the Daytonas from APS are being sold better. APS factory equips a Shanghai 4130 movement in the watch, I still have not received any reviews about the stability of this movement, after all, it just came out two months ago.
