Imo it would be beter not to use white paint for the perpetual calendar.
I suppose it is paint on the backside of the saphire.
I think it would be better if tke months and day would be engraved in the
backside of the saphire. Leaving a matte finish it would imo be nicer
than white paint.
That aside...... What an amazing piece. Khalid, you have a magnificent
collection but this blows the rest away.
Really superb!
