Nice one Mike, I just finished this one. A 2000 LCD that needed a battery and strap. Energizer CR2016 cost me $1.99 at local supermarket. Strap was taken off a dollar store watch "yeah it fits great and only cost a buck".
I alos changed the buckle from plastic to stainless. A little brasso to remove the fine scrathes on the lens and bam!
the stem sets the time\date and alarm too.
