I have owned this watch for 2 years it has held up well and still functions great.  Not sure why the other 2 raters are focusing on details that don't really have anything to do with the function or the Quality of the watch.
As for the "Necklace" if you don't understand its propose you don't know much about the older style dive watches.

The Watch is big and the colors show up and I get lots of positive comments.  The rubber strap helps keep the wt down and is comfortable to wear.
Yes it is a Japan movement but I have not had an issue with it.  Have to say it as good as all those Rice bikes I own that run forever
