Yes, the sleeved seat tube and the curved shape at the top of it are in the 1993 style, although I think the colour scheme is more commonly found on 1994 bikes, including on C16Rs. So I suppose it could be that the frame was built in 1993, but not painted and sold until the following year.
The Clockwork/C16R was always a top-quality ride, far beyond its price, and well worth a sympathetic restoration.
