Thank you very muchIt's 1898 based on the datemark, and it's an english (obviously) lever escapement.
I apologise that I don't have time this moment to do some more looking, but I googled Rotherhams London and found quite a few sources and threads on here you might want to check outThank you very much
Because each assay office had its own specific series of date mark letters, the first thing to look at when interpreting English hallmarks is the town mark, which in this instance is Birmingham, (the anchor), and which changed its letter each year in July, so your case could have been assayed in either of the two years mentioned by John. The font and the shape of the cartouche are also relevant when establishing a date, because it's hard with some letters to distinguish between uppercase and lowercase.It's 1898 based on the datemark,
Hi yes that is the serial number on the watchYour watch was made and cased by Rotherhams in their Coventry works. The case is hallmarked Birmingham 1927/28 and carries their maker's mark.
Can you please confirm the serial number? - I believe it to possibly be 408185, which would be compatible with the case hallmark date.
It is a typical Rotherhams three-quarter plate keyless going-barrel movement of the period, jewelled to the 3rd. There is a cap jewel on the balance; your photographs are not of sufficient resolution to confirm, but possible the lever and escape are also capped. The escapement is a single-roller detached lever escapement with a ratchet-tooth escape; it has a compensation balance, carrying a balance-spring with overcoil.

Ah yes, my apologies, I accidently clicked on the London datemarks chart rather than Birmingham one. Also looking at the correct chart, it's surprising how similar the 1902/27 marks are.Hi netsch20,
