ENQUIRE ON WHATSAPP

An intersection of Vallée de Joux watchmaking and interstellar history. This 39mm Jaeger-LeCoultre Master Calendar Ref. Q1558421 features a dial cut from the prehistoric Muonionalusta meteorite, discovered in northern Sweden and formed over 4 billion years ago in the asteroid belt between Mars and Jupiter. Because each cut exhibits its own natural crystalline Widmanstätten patterns, no two dials are identical. A complete 2018 Full Set, it arrives with its original presentation box, guarantee papers, original setting stylus, and original JLC black alligator leather strap, currently mounted on a handsome brown leather strap. Driven by the manufacture automatic Calibre 866 featuring a complete triple calendar with moon phase, this reference is now discontinued.

The Story

The Story: 4 Billion Years of Cosmic History on the Wrist

The Jaeger-LeCoultre Master Calendar Meteorite (Reference Q1558421) transforms traditional astronomical complications into a literal celestial artifact. The dial is sliced from an authentic fragment of the Muonionalusta meteorite: a metallic asteroid fragment that formed over 4 billion years ago during the birth of our Solar System, entered Earth's atmosphere approximately 800,000 years ago, and was discovered north of the Arctic Circle in Sweden in 1906. Slicing and treating this ancient ferrous material requires extraordinary technical skill; each dial reveals a completely unique Widmanstätten crystalline structure formed over millions of years of microscopic interstellar cooling. No two pieces are ever identical.

The Craft: 39mm Steel Proportions & In-House Calibre 866

The 39mm stainless steel case features classic Master Control proportions, measuring a slender 10.6mm in thickness with sweeping tapered lugs, mirror-polished bezels, and satin-brushed flanks.

The meteorite dial is framed by applied faceted dart indices and dauphine hands, finished with brushed and polished facets for optimal legibility:

  • 12 o’clock: Dual aperture windows cleanly displaying the day of the week and month.
  • Perimeter Track: An outer date ring traced by a central blued-steel hand tipped with a bright red/blue crescent.
  • 6 o’clock: A running sub-seconds track encircling a deep blue polished disc showing the phases of the moon.

Through the sapphire exhibition caseback, you can admire the Manufacture Jaeger-LeCoultre Calibre 866/1. Subjected to JLC's rigorous 1,000 Hours Control quality testing, this 305-component self-winding movement features a 22K gold rotor weight, circular Côtes de Genève stripes, blued screws, and circular graining, operating at 28,800 vph with an approximate 43-hour power reserve.

Condition, 2-Strap Versatility & 2018 Complete Package

This collector piece is presented in Mint condition, displaying crisp case geometry, razor-sharp lugs, and clean sapphire crystals on both faces. The watch is currently styled on a supple brown leather strap that warms the metallic grey tones of the meteorite, and includes the authentic, original Jaeger-LeCoultre black alligator leather strap with its signed stainless steel deployant clasp.

The timepiece arrives as a True Complete 2018 Full Set, including its original JLC presentation box, outer box, operating manual, guarantee certificate dated in 2018, and the original calendar-setting stylus pusher. This discontinued meteorite Master Calendar is an irreplaceable collector trophy.
