About this watch

The Longines Master Collection 40 Chronograph Calendar is a symphony of craftsmanship and technology. This stunning timepiece beautifully blends tradition with modernity, featuring an elegant design suitable for various occasions. Its sleek black dial, adorned with guilloché patterns, creates a striking contrast against the polished stainless steel case. The watch strikes a perfect balance between boldness and wearability, making it an ideal companion for both formal and casual events. Underneath its luxurious exterior lies the powerhouse of the watch: the Longines caliber L687.2. This automatic movement boasts a column wheel and an impressive power reserve of 54 hours, allowing you to not have to wind your watch for nearly two days. The chronograph function enables precision timekeeping, while the moonphase indicator adds a dash of astrological charm. With a water resistance of 30 meters, this watch can withstand splashes and brief immersion in water, making it perfect for daily wear.
