Available now on auction by Second Vintage This distinguished Longines from the 1970s is a brilliant representation of classic Swiss dress watch design, elevated by the unpredictable and stunning passage of time. Powered by the incredibly slim and reliable manual wind caliber 847.3, this timepiece was originally crafted to slip effortlessly under a tailored cuff. Today, it stands out as a completely unique collector's piece thanks to an extraordinary, naturally formed patina across its textured dial. Watches from this era reflect a period when Longines was perfecting ultra-thin mechanical elegance, and this specific example offers a distinct personality that simply cannot be replicated by modern manufacturing. Brand: Longines Reference Number: 4027-8 Serial Number: 52625103 Movement: Manual Wind, Caliber 847.3 Dial: Vertically brushed texture exhibiting heavy, striking amber and golden patina with painted Roman numerals Case Size: 33 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970s Condition: Good vintage condition featuring a dramatic and uniquely patinated dial Dial and Hands The dial of this Longines is an absolute visual standout, presenting an incredibly unique and attractive patina that defines the character of the watch. Originally finished with a fine vertical brushing, the surface has aged to develop deep, warm golden and amber tones. This intense oxidation follows the vertical striations of the underlying texture, creating a remarkably organic appearance reminiscent of aged wood grain or antique parchment. While this represents significant environmental aging rather than a pristine factory finish, the resulting coloration is highly uniform in its direction and undeniably gorgeous. The painted black Roman numeral indices remain crisp and legible against the patinated background, matched by the classic Longines text and winged hourglass logo positioned below the twelve o'clock marker. The Swiss Made text is clearly visible at the bottom edge. A pair of elegant, blackened stick hands display the time with excellent contrast, showing only faint signs of surface aging near the central pinion. Case and Crystal The stainless steel case features a classic, minimalist profile that wears beautifully on the wrist. The design utilizes a seamless integration between the lugs and the central case body, with a sharp transition separating the vertically brushed upper surfaces from the highly polished case flanks and smooth, flat bezel. A visual inspection reveals honest signs of wear, including superficial scratches and minor handling marks consistent with decades of careful use, but the case retains strong factory lines and has not been subjected to heavy over-polishing. The snap-on caseback is cleanly finished with circular brushing and bears the serial number 17 600706 crisp and legible on the exterior. A clear crystal sits slightly above the bezel, protecting the dial and providing an unobstructed view of the striking patina within. Movement Inside the slim case beats the Longines Caliber 847.3, a beautifully engineered 17 jewel manual wind movement. The rhodium plated bridges feature precise linear brushing and golden engravings, displaying the movement serial number 52625103 prominently. The movement is remarkably clean visually, retaining a bright and highly preserved appearance that contrasts beautifully with the heavily aged dial. Running and operational, offering reliable vintage performance, the timegrapher results indicate a healthy daily deviation of +13s to +20s/day. Strap The watch is fitted with a robust and stylized brown leather strap that perfectly complements the golden tones of the dial. The strap features thick contrast stitching, darkened edges, and diagonal tooling marks that enhance the vintage aesthetic. It is secured by a polished stainless steel pin buckle, completing the striking presentation. Condition This timepiece is presented in good vintage condition, offering a truly unique aesthetic. The stainless steel case is well preserved, showing normal vintage wear and fine surface scratches while maintaining sharp original geometry. The highlight of the watch is undeniably the dial, which exhibits heavy, concentrated aging and oxidation. Far from a defect, this intense vertical patina has transformed the watch into a uniquely beautiful piece of art. The manual wind movement is highly preserved and fully functional. Dimensions The watch features traditional mid century dress watch dimensions, measuring 33 mm in diameter excluding the slim winding crown. The ultra thin profile provided by the manual wind caliber allows the case to sit incredibly flat against the wrist, ensuring an elegant and unobtrusive wearing experience that remains highly refined by modern standards. Remarks It is rare to find a dial that has aged with such dramatic and cohesive beauty. This Longines offers the perfect intersection of dependable Swiss mechanical horology and one of a kind vintage character. It is a fantastic opportunity for a collector who appreciates the wabi sabi aesthetic and the entirely unique results of natural oxidation over half a century. History Longines has long been celebrated for its mastery of elegant dress watches and exceptional in house calibers.
