Description

Taking the HM Perpetual Moon to higher heights, Arnold & Son offers three very distinct versions for today's discerning clientele. The Elegant model - the present version - is created in 18-carat red gold with an incredible blue guilloché dial in a stylized sunray pattern, blue guilloché moon disc with golden stars and the hand-engraved moon. The Classic model, also crafted in 18-carat red gold, features a cream-colored dial with a blue guilloché moon disc with golden stars and the hand-engraved moon. The Modern model is created in stainless steel and features a black guilloché dial with black guilloché moon disc with the hand-engraved moon. Each timepiece is accented with a hand-stitched alligator strap. In all, the HM Perpetual Moon is a beguiling work of technical mastery and fine art.

A. Lange & Söhne Saxonia Box + Papers 2021

CHRONO 10:10 did an excellent job indeed. From the feedback to the purchase offer that was given within the hour on a Sunday to the updates regarding the shipment - the service was spot on all the way. The watch arrived in less than 24 hours after being sent (Destination: Germany) and was packed up very diligently with bonus items added. A small misunderstanding was handled very professionally and the costs were kindly covered by CHRONO 10:10 - no questions asked.
