Constructed in stainless steel, the rectangular case is framed by a diamond-set bezel that extends across its entire perimeter. The stones are meticulously arranged to maximize brilliance while maintaining symmetry. The dial features a refined sunburst finish, paired with applied hour markers and luminescent hands for visibility. Internally, a quartz movement provides consistent accuracy with minimal intervention. The integrated bracelet, finished with alternating brushed and polished links, enhances both comfort and durability. Sapphire crystal protection ensures scratch resistance, while the overall case design supports practical daily wear.

The emphasis here shifts toward visual presence. The expanded diamond coverage elevates the watch into a more jewelry-focused expression, while the steel construction preserves a modern, wearable balance.

Patek Philippe Twenty~4 4910/1200A-001

Reference: 4910/1200A-001
Collection: Twenty~4
Case: Stainless steel
Case dimensions: 25.1 × 30 mm
Thickness: 6.8 mm

This is a later-generation evolution of the original Twenty~4 cuff design. Patek Philippe introduced the 4910/1200A-001 in 2020, replacing the earlier Roman-numeral 4910/10A-001 while retaining the characteristic rectangular, Art Deco-inspired case architecture.

Dial

Color: Blue sunburst
Numerals: Applied white-gold Arabic numerals at 12 and 6
Hour markers: Applied white-gold trapeze-shaped markers
Hands: Rounded baton-style white-gold hands
Luminescence: White luminescent coating.

This represents a significant design change from the original 4910/10A generation: Roman numerals and diamond hour markers were replaced by applied Arabic numerals and trapeze-shaped hour markers. Patek Philippe explicitly describes this as the first major modification to the original 1999 Twenty~4 design.

Official current specification: approximately 0.47 ct.

Patek Philippe’s 2020 launch documentation gives the diamond specification as approximately 0.42 ct, while the current technical page states approximately 0.47 ct. We should preserve this discrepancy rather than silently choosing one figure: 0.47 ct is the current factory technical specification; approximately 0.42 ct appears in the original launch documentation.

Official alternative references

The immediate alternatives are:

* 4910/1200A-010 — stainless steel, gray sunburst dial with black-gradient rim
* 4910/1200A-011 — stainless steel, olive-green sunburst dial

Patek Philippe’s current technical documentation confirms both as members of the same 4910/1200A family.
