Invicta Excursion Chronograph Blue Dial Two-tone Men's Watch 80382

AR Coating
So I was wondering, and I would like to hear other's input on this. If the sole purpose of providing a sapphire crystal on a watch is to prevent, and in many cases, eliminate the crystal from being scratched, why is anti-reflective coating applied to its outer surface? I can't seem to understand this. Granted it may provide a higher degree of readability in certain circumstances, but over the long run (years or even decades), it may cause perceivable scratches and imperfections on the crystal that are NOT covered under warranty. An example of this is the Planet Ocean. I own a SMP 2254 and this piece only has AR coating on the underside of the crystal and the dial can be seen perfectly in many and almost all circumstances. So, it seems like coating both sides of a sapphire crystal has no benefits, but rather only shortcomings. Any thoughts?

I got few watches - any help is welcome
Hi, This is what I posted on other forum:Hello,Recently I inherited small collection of wrist watches. There are 20+ (edit: realy there is 17 pieces ¨C at first pile seemed bigger ) watches in collection and brands are Tissot, Favre Leuba, Vulcain, Juvenia. I was told that watches are aprox. form period 1970-1990 (edit: one Tissot I opened is from around 1965 acording to movement). Some have, I think, original straps (marked strap and buckle) and some even have price/stock tags. On top of that I got some literature and catalog. As total newb to watches I would appreciate some guidelines from experienced people. Most of collection are mechanical watches and few are battery powered. I will probably left few pieces as sentimental value and rest will be traded or sold. In literature I got I failed to find any piece from collection, in there are many pieces from same brand and with wide range of prices but not one from collection. I went to local watchmaker but he wasnt able to help me, exc

Thanks Timesofplenty
Scott sent me out a Z-22 Seiko strap for my Monster absolutely free. I got it today nicely wrapped and Scott even included a set of Seiko fat spring bars. I am going to put it on the Monster for a change of pace this weekend.Thanks Scott!
