PeugeotWomen's Classic 14Kt Gold Plated Watch, Rectangular Tank Shape Case with Leather Band and Easy to Read Dial

Q: What are the dimensions of this item?

The leather strap is 8 inches or 20.4 centimeters long (exclusive of buckle). The face of the watch is 13/16 of an inch wide (2 centimeters) and 1 3/8 inches long (3.5 centimeters), 5/16 inches deep or .8 centimeters deep. I love mine! Hope this is the information you were looking for.

Q: how long does it take for the "gold plating" to start fading?

So if the gold fades, it's not real 14k gold

Q: How many mm is the watch band trying to replace my old one ?

Please submit your answer to the seller, I do not know. I returned my watch because it fogged up when I stepped outside into Florida humidity and I I did not think if it did that on the first day that it would last very long especially if it got a little bit wet. But it is a beautiful watch. If you're just trying to replace your band you can search for the size you need and the color that you want.

Q: how long does the battery last?

I don't know how long the battery lasts since the gold finish around the face starting peeling off after I'd had the watch just over a month so it couldn't be returned. I've worn TIMEX watches for most of the last 40 years and never had any finish peel off. This is a cheap, cheap watch.
