Reference 1368480 belongs to the Ultra-Thin Master series from Jaeger-LeCoultre, and this replica ultra thin master 1368480 carries forward the collection’s defining characteristic: a case profile built around one of the slimmest automatic calibers the manufacture produces. The 1368480 dial layout introduces elements that differentiate it from the most pared-down references in the range, including applied indices and a date function that sits within the overall thin case envelope. Where some Ultra-Thin Master references strip everything back to hours and minutes, this one adds just enough functionality to make it a daily-wear candidate rather than a purely formal piece.

Technical Overview

• Reference: 1368480
• Case material: stainless steel
• Profile: ultra-thin automatic
• Crystal: sapphire
• Dial: applied indices with date
• Movement: slim automatic caliber
• Functions: hours, minutes, date
• Strap: leather

Adding a date complication to an ultra-thin movement requires careful engineering because the date disc and its driving mechanism add height. The 1368480 manages this without visibly thickening the case, which speaks to the caliber’s architecture.

Inside the Movement

The slim automatic movement in this reference uses a micro-rotor or peripheral winding system to keep the total stack height within ultra-thin parameters. Conventional full rotors would push the caseback outward, so the caliber design works around that constraint. Jaeger-LeCoultre has been refining thin automatic movements since the mid-twentieth century, and the 1368480 benefits from that accumulated engineering knowledge. The 1368482 blue strap edition shares the same movement platform but shifts the aesthetic with a colored strap and potentially a different dial finish. Both are housed within the broader Ultra-Thin Master lineup, which covers simple time-only layouts through to moon phase displays.

What Sets It Apart

The 1368480 occupies the middle ground within the Ultra-Thin Master range: more functional than a pure two-hand reference, but still committed to the slim-case mandate. The date window adds practical value for everyday use without compromising the architectural intent. This replica ultra thin master 1368480 finds that balance between wearability and thinness that makes the Ultra-Thin Master concept work as more than a showcase piece.
