Jaeger-LeCoultre Q114258J Master Ultra Thin Perpetual Calendar Pink Gold Gradient Blue Dial Watch

Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar – Ref. Q114258J

The Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Ref. Q114258J is a graceful embodiment of haute horlogerie tradition. With its 39 mm 18-carat pink gold case, striking midnight blue dial, and full perpetual calendar complication, it is a watch that combines elegance, technical mastery, and timeless style. Designed for collectors who appreciate both refined aesthetics and advanced functionality, this timepiece stands out in the Master Ultra Thin collection.

Elegant Case Dimensions

The case is forged in polished 18-carat pink gold, measuring 39 mm in diameter and about 9.2 mm thick. With elongated lugs and a bezel that gently catches the light, it retains a refined profile that slips comfortably under a cuff. Water resistance is 5 bar (≈ 50 meters), sufficient for everyday wear. The sapphire case back reveals the movement architecture and finishing.

Midnight Blue Dial Signature Design Details

Under sapphire crystal, the dial features a radiant midnight blue sunray-brushed (gradient blue) finish that accentuates every sub-dial. The perpetual calendar functions—day, date, month, and four-digit year—are laid out with clarity and balance. At 12 o’clock sits the moon phase, surrounded by elongated appliqué hour markers and dauphine hands in gold, polished and satin-finished. The sub-dials have a double opaline finish: opaline on the outside and azure inside, adding layering and visual depth.

Movement Technical Mastery

At its heart beats Jaeger-LeCoultre Calibre 868/1, an automatic perpetual calendar movement. With 330 components and 46 jewels, it delivers a 70-hour power reserve while remaining remarkably slim at about 4.72 mm in height. It operates at 28,800 vph (4 Hz), with reliable performance and precision. The perpetual calendar in this model automatically adjusts for months of varying length including leap years, and the date need not be manually corrected until the year 2100.

Strap Wearability

The Q114258J comes fitted with an alligator leather strap that matches the deep blue tone of the dial, secured by a pin buckle in 18-carat pink gold. Lug width is 21 mm. The strap is interchangeable, offering versatility in styling. The dimensions—39 mm diameter, 9.2 mm thickness—strike a balance between presence and wearability, making it suitable for both formal and more dress-casual settings.
