Hi Neet
Good to be here and I love the Beau Brummell releases as well, they are a fantastic looking watch!
Yes the back looks to be well worn down and may prove to be in need of replacement. It has not arrived yet for me to inspect and have checked over, as I have only just purchased it.
If it needs replacing is there a reliable source you can recommend and does changing it out affect the overall watch aesthetic?
You are correct in that my guesstimate on the date is from the movement, but as I know very very little about these watches I welcome your input and experience.
From the little research I have done it seems as though there are a range of 17 23 21 and 30 Jewel varieties in this watch, not all of which I have seen ads for.
Look forward to any more insights and when it arrives I will update a few more pictures.
Warm regards
Darren
