A Warm New Look: The Master Ultra Thin Date & Moon In Grained Copper

MRSTATELESS JAEGER-LECOULTRE, NEW RELEASES 2025, Dress Watch, Limited Edition, Moon Phase 0

Jaeger-LeCoultre expands its Master Ultra Thin collection with two refined stainless-steel models: the Master Ultra Thin Date and the Master Ultra Thin Moon. Both watches stay true to the principles of elegant watchmaking, combining thin cases, balanced proportions and understated complications. Their most notable introduction is a new grained copper-coloured dial, which brings a warm, contemporary aesthetic to the classic collection.

A Slim and Balanced Case Design

Both models come in 39 mm stainless-steel cases with the clean lines and gentle curves that have long characterised the Master Ultra Thin family. Although they share the same diameter, their thickness differs slightly due to their respective movements. The Master Ultra Thin Date measures just 7.89 mm in height, while the Master Ultra Thin Moon stands at 9.30 mm. The polished finish highlights the slender profile of the cases and contrasts with the textured dial surface, while the softly curved lugs ensure a comfortable fit on the wrist and reinforce the minimalist, dress-watch identity of the collection.

New Grained Copper Dial With Refined Details

The most striking element of these releases is the new grained copper-coloured dial. Its warm tone and fine matte texture introduce a modern character while maintaining the understated nature expected from the Master Ultra Thin line. The applied hour markers are shaped as elongated trapezoids and stand out clearly against the copper background. They are paired with faceted Dauphine hands, with one facet polished and the other satin-brushed to enhance legibility and add a subtle visual contrast. A discreet black minutes track and matching black inscriptions complete the layout, creating a harmonious balance between contemporary texture and timeless elegance.

Date and Moon Phase Displays

On the Master Ultra Thin Date, the calendar indication appears in a rectangular window positioned at 6 o’clock. The aperture is framed with a thin black outline, and the date numerals are displayed on a white disc for clear readability. The Master Ultra Thin Moon introduces a different arrangement by integrating both the moon phase and date into a recessed sub-dial at 6 o’clock. A steel hand points to a smooth copper-coloured date ring, while the moon phase is depicted on a deep blue night-sky backdrop featuring a silver moon that accurately tracks its cycle. This combined display enriches the visual complexity of the dial without compromising its balance.

In-House Automatic Movements With 70 Hours of Power Reserve

Both models are powered by Jaeger-LeCoultre’s latest-generation automatic movements. The Master Ultra Thin Date is equipped with the calibre 899, while the Master Ultra Thin Moon uses the calibre 925. Each calibre offers an improved power reserve of 70 hours and features an openworked 18k pink gold rotor. The movements are decorated with traditional haute horlogerie finishes, including Côtes de Genève stripes, bevelled bridges and blued screws.

Straps and Limited Edition Details

To complement their refined profiles, both watches are fitted with brown alligator leather straps secured by stainless-steel folding clasps. These new models are offered as limited editions, with 800 pieces available for the Master Ultra Thin Date and another 800 for the Master Ultra Thin Moon. Pricing is set at € 10,400 for the Date version and € 12,600 for the Moon version.

Conclusion

With the introduction of the grained copper-coloured dial, Jaeger-LeCoultre brings a fresh yet timeless appeal to two of its most emblematic ultra-thin models. The combination of sleek construction, refined complications and meticulous finishing makes these limited editions compelling choices for collectors who appreciate classic design with a contemporary twist.
