PRS Aerotimer?

[Nealywheelie]

Just noticed my Aerotimer is now running slow, i.e. 1 or 2 minutes per day. Is this a battery issue, or maybe something else.
I know very little quartz-wise watches but they normally advance 4 secs when the battery is nearly finished. However, as the 45 has no running seconds, hard to tell. If it's a battery change, where do I source & get fitted a new one.
Thanks folks.

Is there a specific battery code required, or will any battery do?
Thanks.
