Jaeger-LeCoultre Q1308470 Master Ultra Thin Perpetual Calendar Stainless Steel Black Dial Watch

Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar – Ref. Q1308470

The Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar Ref. Q1308470 is a superb expression of technical craftsmanship and refined design. With a 39 mm stainless steel case, ultra-thin profile, and full perpetual calendar functionality housed in a deep black dial aesthetic, this timepiece demonstrates how grand complications can be elegant, wearable, and visually striking.

Case Physical Dimensions

The case is crafted from polished and brushed stainless steel, measuring 39.00 mm in diameter and approximately 9.2 mm in thickness—remarkably slim for a perpetual calendar watch. The watch is water-resistant to 5 bar (≈ 50 meters), offering protection in everyday, non-submersive settings. A sapphire crystal front and exhibition case-back preserve both durability and opportunity for appreciating its movement.

Dial Aesthetic Details

The dial of Q1308470 is deep black, with sun-brushed finishing that gives subtle radiance under light. It features applied baton hour markers, elegant dauphine hands, and a full perpetual calendar layout: day, date, month, year, moon phase. Each sub-dial is balanced to maintain clarity and symmetry. The black alligator strap complements the dial, enhancing the overall elegance of the piece.

Movement Technical Performance

Inside this masterpiece lies Jaeger-LeCoultre calibre 868/1, an automatic perpetual calendar movement. It beats at 28,800 vph (4 Hz), with 46 jewels among its architecture. Although JLC lists a power reserve of about 38 hours, the thinness (≈ 4.72 mm for the movement) and craftsmanship make this movement a refined, efficient performer. The perpetual calendar complication handles day, date, month, year (including leap years), and moon phase with precision.

Strap, Buckle Comfort

Q1308470 features a black alligator leather strap with a stainless steel double folding buckle. Lug width is 21 mm; standard strap lengths are approximately 75 mm on the 12 o’clock side and 120 mm on the 6 o’clock side. The strap is interchangeable, allowing users to modify aesthetics without altering the case. Together with the moderate thickness and elegantly curved lugs, the watch balances presence with comfort.
