The 4815 sits in an under-documented corner of Patek Philippe's ladies' catalog. Production ran through the 1990s in limited volume, and the reference rarely surfaces with box and papers intact. The cushion-shaped case in 18k gold, the hand-woven integrated bracelet, and the cream dial with diamond indexes on the 4815/3J variant reflect the kind of quiet finishing that Patek applied to its boutique-era ladies' pieces. Because the 4815 has never had the marketing exposure of the Twenty-4 or the Calatrava ladies' lines, acquisition prices have historically been more approachable than the prestige of the piece might suggest.

Every 4815 we offer is inspected by our in-house authentication team, which verifies the movement, case, dial, and bracelet against known Patek Philippe specifications for the reference. We confirm caliber E15 integrity, check that the case-back screws and signing on case, dial, and movement are correct, and document box and papers status. Each piece then carries The 1916 Company's 2-year warranty. If you have questions about a specific example, contact us directly before you inquire.

Both variants share the 21 x 23 mm cushion-shaped case in 18k yellow gold, the caliber E15 quartz movement, and the hand-woven integrated bracelet. The primary distinction is diamond setting: the 4815/3J features 88 round diamonds on the lugs and four bracelet links, plus 28 round diamonds on the bezel. The 4815/1J carries a plain polished bezel without stone setting, making it the cleaner, slightly more wearable of the two. White-gold versions cataloged under the 4815/3 designation also exist from the mid-1990s. Box and papers status varies by example and is confirmed during our authentication process.
