Jaeger-LeCoultre Master

Design
The Jaeger-LeCoultre Master Ultra Thin Q1303520 is a spectacular watch for men, which has a combination of an ultra-thin make and quintessential complications of watch making. Its 39 mm round case has a thickness of just 9.2 mm, which contains a perfectly balanced dial showcasing several impressive functions.
Polished in 18 carat white gold, the case houses a silver dial with recessed silver sub-dials. The index hour markers and the dauphine shaped hour and minute hands feature a silver finish, while the seconds hand is blue coloured.  Beneath the 12 o’ clock position, the moon-phase window (which indicates the phases of the moon through 29 1/2 days) is situated, along with the JL logo and signature.
The day of the week sub-dial is located at 9 o’ clock, the month sub-dial at 6 o’ clock, the date sub-dial at 3 o’clock. The year window is placed between the 7 o’ clock and 8 o’clock positions. Once you set the perpetual calendar and time functions of the timepiece, it will need no adjustment till 2100. Sapphire crystal safeguards the dial and makes it shatter proof and scratch resistant.  The black crocodile leather straps feature a tang buckle at the end.

Features
Beating at 28,800 vph, the Jaeger Le-Coultre Caliber 868 gives impeccable timing. The timepiece contains 46 jewels and is composed of 336 parts, which showcase the chronograph, perpetual calendar, moon phase, and date functions. It has approximately 43 hours of power reserve and is water resistant up to 50 metres.
