The replicas work.. since you're looking for an 111h, I am assuming you are looking for mechanical replicas?
These mechanical watches follow the same rule of any mechanical contraption (including genuine watches too): they have mechanical parts that will be subject to wear and tear. In the case of replicas, the Quality Control is not very good, so the 'engine' so to speak, will be sometimes dirty, sometimes clean, sometimes lubed, sometimes dry..
All these questions are not hard, but can be found if you frequent the forums for, well, say 3 days and you invest time in researching around it; your questions have been asked frequently by other forum members in the past.
I was once a newbie too, and still am a newbie in many areas, but do take your time and slowly digest the information this site has to offer.
Cheers and welcome!
