A FINE AND RARE 18K YELLOW GOLD PERPETUAL CALENDAR WRISTWATCH WITH MOON-PHASES AND RED DOT ARABIC LEAP YEAR INDICATION
1982 REF 3450J MVT 1119616 CASE 2788640
Production of reference 3450 began in 1981 and ceased in 1985. It appears that in total just 244 pieces were made. As the successor to reference 3448, the cases of the two references are slightly different. Manufactured by different case makers, the 3450 has a thicker bezel and sapphire crystal. In addition, the reference 3450's snap case back is some 2mm smaller than that of the reference 3448.
For an example of this reference, see Huber & Banbery, Patek Philippe Wristwatches, Vol. 2, Second Edition, p.290, pl.499a.
It is extremely rare to find a reference 3450 from the original owner accompanied by all its documents. The watch appears to have been untouched over the last 25 years and is in outstanding condition.
