I would like to take this opportunity to take a more informal approach when reviewing the watch, as such you will be allowed to ask any questions related to this watch. First, I would like to talk more about this watch specification as described by most dealer:
Name: Breitling Avenger Skyland Blacksteel M13380 Replica
Movement: Asian 7750, 28800bph
Crystal: Sapphire, double sided AR coated
Case: Treated Stainless Steel Case (more about this later)
Caseback: Stainless Steel (153/2000)
Straps: Rubber with Breitling Diver's style tongue buckle (on the piece above, it's genuine Breitling Calf, tongue buckle).
This watch has been around for quite some time. However, at the beginning, I feel that the price was really steep hovering at 428USD. Recent introduction by one of the dealer here, brought down the price quite considerably. Nevertheless, please take note that there are at least 3 versions of this watch on the market made by at least 2 makers. I would not go into details on the differences but if you are interested, feel free to ask.
Out of the box, the watch comes with rubber straps. This, while it looks pretty much like the genuine Breitling strap, is still not up to genuine standard. The smell of vanilla is present on this one. Exact same smell like you will get from Chopard Mille Miglia GTXL Grey Chrono limited edition. This makes me believe that this watch comes from the same factory as that Chopard. There are other makers who make this watch and it smells differently. The strap feels softer than the genuine strap but slightly thicker. The genuine does not have any smell (neutral). The rep strap is nonetheless feels pretty comfortable on the wrist.
A minor problem appears when I received the watch. The rotor seems to be quite loose and making screeching sound as if it touches the caseback. It seems that there was a pretty big sticky dirt on the inner side of the caseback. This needs to be cleaned. Nonetheless, the problem was gone after cleaning the caseback and tightening the rotor screw just to be sure.
Movement wise, it has been running about 40 secs fast a day. That's far too much IMHO because most of the Asian 7750 that comes out of box usually is about 10 secs fast a day and it will stabilise nearer to 5 secs fast a day after a couple of weeks of usage. Nothing to complain on the chronograph and datewheel, they are very good. Chrono second hand doesn't stutter and glides upon starting like a ballerina on ice-skating ring. Minute counter changes exactly like the ETA7750, that is to say, it changes when the chrono second hand is passing through the 60 seconds mark.
The case seems to be of the same quality as the Avenger Skyland, except this one feels more refined when unscrewing and screwing the crown. Best point of having the case treated with dark grey-black coating (definitely the same colour as the genuine, much like IWC Top Gun Ceramic Chrono colour), the case has brushed finishing. This does not attract scratches, etc and certainly the coating or maybe the heat treated case looks exceptionally well made to withstand scratches. Think of it as Tegimented steel like what Sinn/SUG has done to some watches. This alone justifies the extra dollars spent on this watch. Take note that this watch has already been priced under 300USD.
So, that's all for these aspects, you may wish to ask further about smaller details. The bottom line is, this watch is worth what it is priced today. I doubt it will go any lower than what we have seen. No modification required except the lume on hands, dial and pearl. However, owning many watches with great lume, it's only a cosmetic issue rather than a practical one. So, no reluming on this piece to me. Just wear it as it is, when it breaks, just put another movement in it. Well done!
This will give you hints on what will come next
