18ct GOLD VINTAGE POCKET WATCH

HI I HAVE A VINTAGE 18ct GOLD HALF HUNTER POCKET WATCH , THE WATCH IS ENGRAVED ON THE INSIDE COVER PLATE 1899 AS THE YEAR IT WAS PRESENTED , THE WATCH IS HALLMARKED ON EVERY PLATE COVER AND ON THE WINDER WITH THE CROWN & 18
OTHER HALLMARKS ARE AN ANCHOR ON ITS OWN & IT LOOKS LIKE A D OR A FANCY P , BUT I WOULD SAY IT S A LETTER D ,
ALSO THERE IS THE LETTERS W.E & 3 UNDERNEATH THE LETTERS ,
THERE IS NO MAKERS NAME ON THE WATCH FACE OR ANYWHERE ELSE .
IVE LOOKED IN THE LIBRARY AND FOUND THAT THE W.E MIGHT BE W. EHRHARDT ,
THE WATCH WEIGHS 140 GRAMS , I ALSO HAVE A 9ct ALBERT CHAIN FOB WITH SPINNING FOB IN BLOODSTONE AND A RED STONE ON THE OTHER SIDE , THE CHAIN IS HALLMARKED ON EVERY LINK AND WEIGHS 50-6 GRAMS , SO WHEN ITS ON THE WATCH THERE IS A TOTAL WEIGHT OF 190 GRAMS
ON THE T/BAR OF THE CHAIN IT IS STAMPED EITHER
W & C . OR WLC. CAN YOU HELP ME HERE PLEASE TO IDENTIFY THE MAKER AND THE EXACT AGE OF THE WATCH , AND WHAT I FEEL WAS MOSTLY UNUSUAL WAS THAT THERE IS NO MAKERS NAME ON THE WATCH FACE OR BACKPLATE ON THE MOVEMENT , EVERY WATCH I HAVE SEEN TO DATE HAS THE MAKERS NAME ON THESE PLACES . THANKS FOR YOR TIME IN HELPING ME , YOURS CHRIS.
