This model combines an elegant gold-plated stainless steel case, hesalite crystal, screw-down case back, and the interesting in-house Longines Calibre 23.ZS movement.\u003c\/p\u003e\n\u003cp\u003eThe presented timepiece has a case diameter of approximately 34 mm without the crown and is equipped with a mechanical hand-wound movement. It boasts classic proportions typical of the 1950s and is also a collectors' item due to its Calibre 23.ZS, a significant movement in Longines' post-war development.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMovement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the heart of the watch is the Longines Calibre 23.ZS – an in-house mechanical manual-wind movement introduced by Longines in the autumn of 1948. This movement is particularly interesting for collectors because it emerged during a crucial period in the brand's history, directly after World War II.\u003c\/p\u003e\n\u003cp\u003eThe Calibre 23.ZS succeeded the older 10.68Z movement. The previous calibre was a very successful design, but by the second half of the 1940s, it required modernization. The 10.68Z movement was introduced in 1925 and was closely related to the even earlier 11.62 calibre. Longines therefore needed a new design to meet the demands of the post-war market.\u003c\/p\u003e\n\u003cp\u003eAt that time, almost half of Longines' production went to the United States, and the brand's American agent had a significant influence on the direction of production in Saint-Imier. It was the needs of the American market and the necessity to modernize older movements that contributed to the development of the Calibre 23.ZS.\u003c\/p\u003e\n\u003cp\u003eThe 23.ZS movement is historically significant as one of the few new movements from a Swiss manufacturer that emerged directly after World War II. Europe was economically weakened at the time, and even the largest watch companies were cautious about major investments in research, machinery, and tooling needed to create an entirely new calibre.\u003c\/p\u003e\n\u003cp\u003eLongines allocated approximately 20,000 Swiss francs to research on the 23.ZS movement and then another 25,000 Swiss francs for tooling to enable its commercial production. This illustrates how important this movement project was for the brand.\u003c\/p\u003e\n\u003cp\u003eThe Calibre 23.ZS was produced in parallel with the closely related 23.Z version. The 23.ZS model features a central seconds hand, while the 23.Z used a more traditional layout with a small seconds sub-dial at the bottom of the dial. Both versions are valued by collectors and hold their place in Longines' watchmaking history.\u003c\/p\u003e\n\u003cp\u003eTechnically, the Longines 23.ZS was a modern construction for its time. The movement was equipped with an anti-shock system and anti-magnetic protection. Both solutions were greatly developed during World War II and subsequently adapted for higher-class civilian watches.\u003c\/p\u003e\n\u003cp\u003eThe movement has 17 jewels, operates at a frequency of 18,000 vibrations per hour, and offers approximately 44 hours of power reserve. Its diameter is about 23.69 mm, the mounting diameter is about 23.3 mm, and the height is about 4.6 mm. The lift angle is 46 degrees.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCase and Dial\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe watch case is made of stainless steel, which has then been gold-plated. It features a classic, round shape and elegant proportions typical of watches from the late 1950s.\u003c\/p\u003e\n\u003cp\u003eThe case diameter is approximately 34 mm without the crown, the width with the crown is approximately 36 mm, the height is approximately 9 mm, and the lug-to-lug dimension is approximately 38 mm. These proportions are typical for elegant vintage watches, which sit well on the wrist and maintain a subtle, classic character.\u003c\/p\u003e\n\u003cp\u003eThe case is styled in a manner characteristic of Longines watches from this period. The gold-plated finish gives it a more elegant, warm, and classic appearance, well suited to a 1950s watch.\u003c\/p\u003e\n\u003cp\u003eThe watch has a screw-down case back and an original crown, which is not signed on this particular piece. The crystal is hesalite, or acrylic. This type of crystal was commonly used in historical watches – it is lightweight, relatively shatter-resistant, and authentically represents the character of vintage watches. While it may be more susceptible to minor scratches than sapphire crystal, its advantage is that it can be polished.\u003c\/p\u003e\n\u003cp\u003eThe dial has a classic layout with a central seconds hand, a result of using the 23.ZS movement. This solution gives the watch a more modern character for its time compared to models with a small seconds sub-dial.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStrap or Bracelet\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe watch is sold in the configuration shown in the product photos.

From the beginning, the brand built its reputation on precision, innovation, and high-quality craftsmanship.\u003c\/p\u003e\n\u003cp\u003eIn 1832, August Agassiz, along with two partners, founded a watchmaking company in Saint-Imier specializing in the production of pocket watches. In subsequent decades, the company grew, and Ernest Francillon played a key role in the brand's history.\u003c\/p\u003e\n\u003cp\u003eIn 1867, Ernest Francillon brought together previously dispersed watchmaking operations under one roof, to a factory located in an area known as \"Les Longines,\" or \"The Long Meadows.\" This name is the origin of today's Longines brand name.\u003c\/p\u003e\n\u003cp\u003eIn the same period, the brand's first movement, designated 20A, was presented, marking Longines' path toward more mechanized and modern watch production. Longines was a pioneer in the industrial organization of production while maintaining high watchmaking quality.\u003c\/p\u003e\n\u003cp\u003eIn 1889, Longines registered its classic winged hourglass logo. In 1893, this mark was officially registered with the International Bureaux, becoming one of the oldest trademarks in continuous use to this day.\u003c\/p\u003e\n\u003cp\u003eThe presented Longines ref. 6393-6 from 1959 fits well into the brand's history. It is a watch from a period when Longines produced its own high-class movements, and the Calibre 23.ZS was an example of the company's post-war technical development.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Information\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBrand: Longines\u003c\/p\u003e\n\u003cp\u003eModel: ref. 6393-6\u003c\/p\u003e\n\u003cp\u003eReference: 6393-6\u003c\/p\u003e\n\u003cp\u003eYear: 1959, according to serial numbers\u003c\/p\u003e\n\u003cp\u003eMovement: Longines Calibre 23.ZS\u003c\/p\u003e\n\u003cp\u003eMovement type: mechanical, hand-wound\u003c\/p\u003e\n\u003cp\u003eSeconds function: central seconds\u003c\/p\u003e\n\u003cp\u003eNumber of jewels: 17 jewels\u003c\/p\u003e\n\u003cp\u003eMovement size: 10.5'''\u003c\/p\u003e\n\u003cp\u003eMovement diameter: approx. 23.69 mm\u003c\/p\u003e\n\u003cp\u003eMounting diameter: approx. 23.3 mm\u003c\/p\u003e\n\u003cp\u003eMovement height: approx. 4.6 mm\u003c\/p\u003e\n\u003cp\u003ePower reserve: approx. 44 hours\u003c\/p\u003e\n\u003cp\u003eOperating frequency: 18,000 vibrations per hour\u003c\/p\u003e\n\u003cp\u003eLift angle: 46 degrees\u003c\/p\u003e\n\u003cp\u003eAnti-shock system: yes\u003c\/p\u003e\n\u003cp\u003eAnti-magnetic protection: yes\u003c\/p\u003e\n\u003cp\u003eCase: stainless steel, gold-plated\u003c\/p\u003e\n\u003cp\u003eCase shape: round\u003c\/p\u003e\n\u003cp\u003eCase diameter: approx. 34 mm without crown\u003c\/p\u003e\n\u003cp\u003eWidth with crown: approx. 36 mm\u003c\/p\u003e\n\u003cp\u003eCase thickness: approx. 9 mm\u003c\/p\u003e\n\u003cp\u003eLug-to-lug: approx. 38 mm\u003c\/p\u003e\n\u003cp\u003eCase back: screw-down\u003c\/p\u003e\n\u003cp\u003eCrown: original, unsigned\u003c\/p\u003e\n\u003cp\u003eCrystal: hesalite \/ acrylic\u003c\/p\u003e\n\u003cp\u003eStrap or bracelet: as per product photos\u003c\/p\u003e\n\u003cp\u003eSet: as per product photos\u003c\/p\u003e\n\u003cp\u003eWarranty: 100-day Dial-House warranty\u003c\/p\u003e\n\u003cp\u003eCondition: used\u003c\/p\u003e\n\u003cp\u003eFor questions regarding condition, operation, set, warranty, or the possibility of viewing additional photos, please contact Dial-House store before purchase.\u003c\/p\u003e","brand":"Longines","offers":[{"title":"Default Title","offer_id":57973291581775,"sku":"DH-008","price":2550.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1018\/2144\/8527\/files\/IMG_3766.jpg?v=1782850251","url":"https:\/\/dial-house.com\/en\/products\/longines-ref-6264-kopia","provider":"Dial-House","version":"1.0","type":"link"}
