Patek Philippe Automatic Open Heart Watch – Black Dial, Rose-Gold-Tone Roman Numerals & Leather Strap

Refined mechanical styling meets timeless dress-watch elegance in this men's automatic open-heart watch. A deep black dial is paired with warm rose-gold-tone Roman numeral markers, a polished matching case and a classic black leather strap for a sophisticated and distinctive appearance.

The open mechanical display at 6 o'clock reveals part of the movement in action, while a decorative 24-hour night-sky subdial near 12 o'clock adds depth and character to the dial. The result is an elegant statement watch suitable for business, formal occasions and premium everyday styling.

Men's Automatic Open Heart Dress Watch

Designed for men who appreciate mechanical watches, this timepiece blends traditional Roman numeral styling with a contemporary open-heart display. Its black and rose-gold-tone colour combination gives the watch a luxurious appearance without making the dial feel overly busy.

A textured black leather strap completes the classic dress-watch design and pairs naturally with suits, business shirts, panjabis and smart-casual outfits.

Product Specifications

Specification notice: The approximately 42 mm case diameter and 12–13 mm thickness are visual estimates based on the supplied photographs. Measure the physical watch and verify the movement, crystal and water-resistance rating before publishing final specifications.

Mechanical Open-Heart Design

Visible Automatic Movement

The circular opening positioned at 6 o'clock reveals part of the mechanical movement underneath the dial. The moving balance mechanism creates a constantly changing focal point that gives the watch its distinctive mechanical character.

Automatic Mechanical Operation

Unlike a conventional battery-powered quartz watch, an automatic mechanical movement stores energy through wrist motion during normal wear. When the available power reserve is depleted after extended non-use, the watch may stop and require restarting and time adjustment.

Elegant Black Roman Numeral Dial

Rose-Gold-Tone Roman Numerals

Applied Roman numeral markers create a traditional luxury-inspired appearance. Their warm metallic finish contrasts beautifully against the deep black dial.

Refined Two-Hand Layout

The elegant central hands maintain a clean and uncluttered presentation, allowing the Roman numeral markers and mechanical display to remain the visual focus of the watch.

24-Hour Night-Sky Style Subdial

The upper subdial includes a 24-hour scale with moon-and-stars styling, adding another layer of visual detail to the dial.

Because the exact movement specification is not available, this should be described as a 24-hour or night-sky style display rather than a true astronomical moonphase complication unless confirmed by the supplier.

Polished Rose-Gold-Tone Case

The warm polished case frames the dark dial and creates an elegant contrast that works particularly well with formal and traditional clothing.

Matching metallic accents on the Roman numerals, hands and crown give the complete watch a coordinated premium appearance.

Classic Black Leather Strap

The black strap features a crocodile-inspired texture and visible edge stitching, giving the watch the traditional character expected from a formal mechanical dress watch.

Traditional Pin Buckle

A classic pin buckle allows the strap to be adjusted across multiple wrist sizes while maintaining the watch's traditional design.

How to Use an Automatic Watch

Starting the Watch

If the watch has stopped after being left unused, gently move it from side to side for a short period. If the movement supports manual winding, the crown may also be used to build initial power.

Setting the Time

Pull the crown to the appropriate setting position and rotate it until the correct time is displayed. Press the crown completely back into the case when finished.

Maintaining the Power Reserve

Regular wrist movement helps keep an automatic watch running. If the watch is left unworn longer than its available power reserve, it may stop and require resetting.
