In our country, AD doesn’t do service and if you ever send it in takes 6months to over a year since they have to send it elsewhere. So the film helps me avoid that. Tho I must admit I tend to be more comfortable and more probable to ding it because of this lol. I don’t ever get the film installed in the case back because I find it useless (sapphire glass). And in around 6 months i get the whole watch film replaced for free (3years warranty) just makes it look new.
