The Jaeger-LeCoultre Master Ultra Thin Moon 39, reference 1368482, pairs a 39 mm stainless steel case with a silver sunray dial and a black alligator strap. The dial carries a moon phase at 6 o’clock and a blued central seconds hand over applied indices, so the only color on the front of the watch comes from that single hand. At 9.9 mm the case still slips under a shirt cuff even though it houses a moon phase and a date indication, which is the whole point of the Ultra-Thin construction. This JLC Master Ultra Thin replica reproduces the Moon 39 layout rather than the plain two-hand dial used elsewhere in the collection.

Case & Movement Specs

• Reference: 1368482
• Case material: stainless steel
• Profile: ultra-thin construction
• Crystal: sapphire
• Dial: silver sunray with applied indices, moon phase at 6 o’clock, blued central seconds hand
• Movement: clone Cal. 925/1, automatic, 28,800 vph
• Power reserve: 42 hours (genuine Cal. 925/1: 45 hours)
• Water resistance: 50 m (same as genuine)
• Functions: hours, minutes, central seconds, date, moon phase
• Strap: black alligator with pin buckle

The black alligator strap is the quietest fitting a silver sunray dial can take: it frames the dial without competing with the moon phase disc or the blued seconds hand. Alligator leather on a pin buckle is the standard strap across the Master Ultra Thin line, and holding to that combination is why this Master Ultra Thin super clone reads as a coordinated piece rather than a case with an aftermarket accessory attached.

Caliber Breakdown

Under the caseback the 1368482 runs a clone Cal. 925/1, automatic, 28,800 vph. Power reserve is 42 hours against 45 hours on the genuine Cal. 925/1, and water resistance is 50 m, the same as the original. The movement drives hours, minutes, central seconds, the date and the moon phase, and at 4.9 mm the genuine caliber is what lets the case stay at the 9.9 mm that justifies the “Ultra-Thin” designation. Strap color does not affect horological performance, but it dramatically affects how the watch pairs with clothing. Black alligator reads as formal across navy, grey, and charcoal wardrobes, which is why it is the default fitting on the steel Moon 39 rather than a special edition. The Reserve de Marche blue dial version drops the moon phase and puts a power reserve indicator on a blue dial instead, so the two references split the same 39 mm case between two different complications. The broader Ultra-Thin Master collection runs from plain date models up to perpetual calendars for those who want less or more on the dial.

How It Compares

Among Ultra-Thin Master references, the 1368482 stands out through its dial rather than its strap. The moon phase at 6 o’clock and the date put two indications on a face that the simpler references leave bare, and the moon phase module has to fit inside a case measuring 9.9 mm front to back. The JLC Master Ultra Thin replica keeps the 39 mm steel case and the clone Cal. 925/1 shared across the Moon 39 line, dresses it on black alligator, and adds a moon phase complication that the plainer references intentionally avoid.

Neutral dials are the ones people keep, which is the argument for looking at every JLC Ultra Thin Master we stock before settling on the 1368482. Our ranking of which JLC replicas are worth the money answers the question that follows: whether a Moon 39 is the right place to start.
