An outstanding model from the Vacheron Constantin Métiers d’Art Mécaniques Ajourées collection represents remarkably well-made and very interesting timepiece. It features very admirable 40mm rounded case 7.5mm thick, made of fabulous 18K white gold, and featuring see-through sapphire crystal case back. The noteworthy dial has gray Grand Feu opaque enameled external ring, while its majority is transparent, so the work of the striking caliber 4400 SQ is visible either through the dial or the transparent case back. The caliber measures 28.6mm diameter and it’s 2.8mm thick; it’s manually wind, holds approximately 65 hours power reserve, and it’s spotlessly detailed-made of 127 parts and 21 jewels, featuring hours and minutes. The strap of this watch is made of very resistant and long-lasting black crocodile leather, combined with standard tang clasp. It’s water resistant to 30 meters.
