Tag Heuer Monza

[woodfell]

Hi,

First posting but I've been following this forum for a while.

I've been offered a Tag Heuer Monza calibre 36 watch by a relative and not sure of its value. The watch is 5 years old and comes with the original leather deployment clasp, presentation box and all papers. It has not been serviced and I think the chronograph functions are not working as pressing the two chronograph buttons do nothing. The watch keeps good time as I've been wearing it for the last day. So, what are the opinions on its value?

Thanks.

Robin
