Longines Tank with Hooded Lugs

Partially verified

This vintage Longines Tank wristwatch, dating to approximately the 1950s, features a square yellow gold case measuring 21 mm in width. The watch is distinguished by its hooded lugs, which are integrated into the case construction to provide a wider profile on the wrist. The dial displays applied hour markers and numerals, set against a surface with natural patina. A central blued steel seconds hand provides contrast. The watch is powered by a manual-winding Longines caliber 8NS movement. The case is constructed from 14-karat yellow gold. The piece is presented as a functional vintage timepiece that integrates specific lug architecture with a classic movement, and it is documented by the provided source as an example of mid-century Swiss watchmaking.

Object description

Case and Lugs

The watch features a square-form case constructed from 14-karat yellow gold. The primary design element of the case exterior is the hooded lug configuration, where the lugs extend from the main body in a continuous, stylized fashion. This design choice is intended to create a broader visual footprint on the wrist, despite the relatively compact 21 mm width of the case.

The geometry of the case reflects aesthetic influences often associated with the Art Deco period. The construction relies on the contrast between the precious metal material and the structural design of the lugs, which serve both as a functional component for the strap attachment and a visual defining feature of the model's profile.

Evidence for this section
  • “استفاده از طلای زرد ۱۴ عیار در ساخت این بدنه”
  • “طراحی خاص بندها یا همان Hooded Lugs است که به شکلی هنرمندانه از بدنه اصلی منشعب شده‌اند”
  • “عرض بدنه: ۲۱ میلی‌متر”

Dial and Hands

The dial is configured with applied hour markers and numerals, which provide physical depth to the display. The surface has developed a layer of natural patina over time. The design maintains a traditional approach to readability and visual balance, consistent with the reported era of the timepiece.

A central seconds hand, finished in blue, functions as a focal point of the dial layout. This application of a heat-treated blue finish serves as a detail within the overall minimalist aesthetic, providing a color contrast against the aging surface of the dial.

  • “اعداد و شاخص‌های اعمال‌شده (Applied) روی صفحه”
  • “پاتینای ملایم و گرمی که در طول سالیان بر روی سطح صفحه نشسته”

Movement

The watch is powered by the Longines caliber 8NS, a manual-winding mechanical movement. This caliber was utilized by the manufacturer during the period in which this watch was produced, serving as the functional core for the piece. The movement is characterized by its simplicity in operation.

The movement choice aligns with the overall design philosophy of the watch, which emphasizes mechanical reliability and straightforward utility. The caliber 8NS is identified by the source as a known and functional driver for timekeeping in this model.

Evidence for this section
  • “موتور کوکی دستی (Manual-winding) کالیبر 8NS قرار دارد”
  • “این موتور به عنوان یکی از پیشرانه‌های محبوب و قابل اعتماد لانژین در آن دوره شناخته می‌شد”

Open research questions

  • Does the internal case back confirm the specific date of manufacture or production batch?
  • Are there any additional hallmarks stamped on the case confirming the 14k gold composition?
