Bicolour Daytona model 16523 with white dial, N430xxx case number from approx 1993. Comes on the Oyster 78363 bracelet which was correct for some early ones like this. Had a movement service and new glass by an Approved Rolex Watchmaker before sale. Not up to museum quality, but a very good value watch when you consider that a NEW one now costs £8,870 !
