1940s Jaeger-LeCoultre "Day-Date" Rare Rectangular Black Unique-Dial in Stainless Steel

Jaeger Le Coultre, "Day Date", rare rectangular model, black dial with unique design, stainless steel, circa 1940s. It is equipped with a rare rectangular Cal.436 with a day-date function. The day-date round model is already rare but the rectangular case is even more rare. The rare black dial, the rouletted luminescent and white printings on the outer and inner circumference, and the red printed pointer date display make this watch very unique and colorful. The black dial still retains its luster and the original luminescence and printings, and the rectangular case retains its characteristic streamlined form, making it a super rare gem.
