The WAC1110 was produced in the mid-2000s, with most examples manufactured between 2004 and 2007. Based on the JA serial prefix, your particular watch is most likely from 2005 or 2006.
The watch battery has a lifetime cover for the battery from Timsons. This battery was fitted and tank tested yesterday (25/07/2026)
I have owned the watch for approximately 10 years.
I do not have the box or any papers with the watch as it did not come with any when I purchased the watch.
There is also some Spare links that will be sold with the watch.
