Breitling Navitimer 1952 QP Perpetual Calendar Chronograph 1

Watches with aerospace-inspired mechanics have made the rounds here on StyleCrave, but one that blends a chronograph and a moon-phase calendar into one piece certainly caught our attention. Only built in a limited edition of 100 units, the Breitling Navitimer 1952 Quantieme Perpetuel not only tells time and the date, it knows what season we’re in, if it’s a leap year or the exact moon phase. A cool complication, what we have in here is an 18K rose gold finished 1952 Quantieme Perpetuel (#8 of 100) that is being sold on eBay with the price stalling at $5,050 as you read.
