Case and Dial Construction

The timepiece features a circular 18k pink gold case catalogued at 43 mm in diameter. Visible inspection confirms chronograph pushers situated at 2, 4, and 10 o'clock alongside a fluted winding crown at 3 o'clock, with the case mounted on a grey textured strap. The dial displays an all-black finish with matching black subsidiary registers positioned at 4 and 8 o'clock, which the source notes differs from regular production models with contrasting white subdials. Central superimposed split-seconds chronograph hands operate over applied Roman markers at XII and VI, accompanied by an up/down power reserve indicator below 12 o'clock and an outer tachymeter scale.

Identity and Edition Background

This A. Lange & Söhne Double Split Flyback wristwatch bears reference 404.047F and case number 163'803, with production catalogued as circa 2005. According to Christie's, the model was executed as part of an edition strictly limited to 10 pieces produced exclusively for the Singaporean retailer Sincere Watch Company. The lot description notes that this execution was preceded in 2004 by another special edition for Sincere's 50th anniversary (reference 404.036 in platinum), which also featured an all-black dial. The auction house notes that the present timepiece was consigned by a private collector.

Reported Movement and Documented Accessories

The watch is reported by the auction catalogue to be powered by the manual-wind caliber L001.1, featuring 465 hand-finished parts, an operating frequency of 21,600 vibrations per hour, a 38-hour power reserve, and the manufacture's first in-house balance spring. However, the movement and case back are not visible in the provided primary image, so these internal details remain unverified by direct observation. Accompanying items listed by the source include an 18k pink gold A. Lange & Söhne deployant clasp and a Proof of Origin document; neither accessory is depicted in the primary photograph.
