The R.E.Robbins watches are all 11 jewels (pillar plate not jeweled) according to the serial number ledger. These movements appear identical to the P.S. Bartlett being produced at the same time, including under sprung hairspring, hidden stud and fake jewel settings (just engraved into the plate). It is unclear why so few, or why any at all, were produced. This example watch has a gold balance and an unsunk AWCo porcelain dial; The A.W.Co silver HC, serial # 6170 has a lion hallmark.
