Longines Watch Master Collection L2.920.4.51.7.  The premium Longines Master Mens watch collection has remained one of the brand’s most successful ranges since it was first launched in 2005. The exceptional detail and impressive functionality that goes into each piece is made clear when you first glance at the quality dial and sleek case. Each Longines Master Collection watch is fitted with a Swiss self-winding movement that can be watched through the crisp sapphire crystal case back. The polished stainless steel case of this Longines Master Collection watch measures to a neat 42mm in size and is fastened effortlessly to the wrist by a comfortable black alligator leather strap and a stainless steel triple security folding clasp. The L897 automatic winding movement delivers exceptional functionality, providing the men’s dress watch with hour, minutes, seconds function, a double day and date window at 3 o’clock and an impressive power reserve of 64 hours. The unique black “barley corn” dial is the perfect backdrop to these functions, decorated in painted Roman numerals, silvered polished hands and the legendary winged hourglass logo.
