The Longines Conquest Calendar Ref. 9005 is a standout example of mid-century Swiss watchmaking, combining elegant design, technical innovation and substantial precious metal content. Produced in 1956, this reference sits firmly within Longines’ golden era and showcases just how refined the brand’s upper-tier offerings were during this period.
Housed in a solid 18K yellow gold case, the watch has a reassuring weight on the wrist that immediately sets it apart from gold-capped or plated alternatives. The silver dial is beautifully balanced, featuring Art Deco influences with arrowhead markers that reflect the design language of the 1950s while remaining timeless today.
At its heart is the Longines calibre 19ASD, an automatic movement with date complication that was considered technically advanced for its time. Smooth, reliable and well-finished, it underlines Longines’ reputation as one of the most respected manufactures of the era.

A Word on Condition
The case remains strong and well-preserved, with clear definition and excellent presence for a watch of this age. The highlight on the reverse is the Conquest caseback medallion, which remains crisp and visually striking. These medallions are often heavily worn or polished flat over time, so finding one in attractive condition adds significant appeal.
The dial presents cleanly with even ageing, and the movement has been fully inspected to ensure reliable daily performance.
Collector Insight
Early Longines Conquest Calendars are increasingly recognised as some of the best value propositions in vintage Swiss watches. During the 1950s, Longines positioned the Conquest line at the very top of its catalogue, competing directly with brands that now command significantly higher prices.
From an investment perspective, the heavy solid 18K gold case provides tangible intrinsic value that underpins the watch regardless of market trends. Unlike gold-capped pieces, these watches contain real weight in precious metal, which continues to support values as gold prices rise. When combined with a respected manufacture, an in-house movement and strong design, it creates a compelling long-term proposition.
Collectors are increasingly turning to watches like this as they look beyond the obvious names and recognise just how much quality Longines delivered during this era.
