Thanks for the interest. I had the pocket watches serviced at Steven Hale by Bond street tube station. Not cheap, but they are quite valuable both sentimentally and monetarily. They are both gold repeaters
the golden coloured half hunter is a minute repeater by Audemars London, it has lovely blued hands and an inscribed back plate.
the silver coloured one doesn’t have a makers mark that I can see. it is a quarter repeater and has my grandfather’s initials on the front (as he signed them) and his name in Chinese on the back (he lived in China from the 20s to the 50s).
