I highly recommend AboutTime for watch repair and service.
Sean serviced and replaced the mainspring on my 1986 Datejust.
He replaced the mainspring on my 1940’s Universal.
He sourced and fitted a hard to find dial for my wife’s 1990’s Oyster no date.
The latest work he carried out for us was to repair our non-functioning Imhof ball clock.
Excellent value and service.
