Tudor has expanded its 1926 collection with the introduction of its first-ever moon phase complication, the 1926 Luna. This release represents a strategic engineering decision, integrating a complex astronomical function into the brand’s most accessible product line by leveraging a proven third-party caliber. The focus is clearly on delivering a specific feature set within a well-defined price architecture, marking a significant technical addition for the brand.
Case Specifications and Proportions
The 1926 Luna is built upon a 39mm polished stainless steel case, featuring a slim profile of just 10.1mm. These dimensions provide balanced and classic proportions suitable for a dress-oriented timepiece. The case is paired with a seven-link bracelet that introduces a practical contrast with brushed outer links against the polished center links. The architecture is completed with a sapphire crystal, ensuring high scratch resistance and optical clarity for the domed, sunray-finished dial.
Caliber T607-9: Engineering and Precision
At the heart of the 1926 Luna is the Tudor Caliber T607-9, an automatic movement based on the Sellita SW280-1. This choice is pivotal to the watch’s positioning. The caliber operates at a standard frequency of 28,800 vph (4 Hz) and provides a 41-hour power reserve. Critically, Tudor regulates these movements to chronometer-grade performance, achieving an accuracy of -4/+6 seconds per day, though without official COSC certification. This level of adjustment demonstrates a commitment to precision while managing production costs. The movement reliably drives the central time display, date wheel, and the moon phase complication positioned at the 6 o’clock mark.
Material Construction and Durability
While elegant in its design, the 1926 Luna incorporates specifications often associated with more robust tool watches. The inclusion of a screw-down crown contributes to a substantial water resistance rating of 100 meters. This engineering choice significantly enhances the watch’s versatility and durability for daily wear, setting it apart from many competitors in the dress watch category which often feature lower resistance ratings. The use of 316L stainless steel for the case and bracelet ensures reliable corrosion resistance and longevity.
In summary, the Tudor 1926 Luna is a calculated addition to the brand’s portfolio. It successfully integrates a moon phase complication by utilizing a well-regarded and precisely regulated Sellita base caliber. The technical value proposition is strong, combining classical aesthetics with superior durability specifications like 100m water resistance, all packaged to meet a competitive market segment.
