Waltham Silver Open-Face Pocket Watch

Partially verified

This open-face silver pocket watch was manufactured by the Waltham Watch Company, featuring a movement produced in the United States and subsequently cased in Britain. The watch is dated to approximately 1929, corresponding to Birmingham hallmarks struck on the sterling silver case. The case, measuring 49mm in diameter excluding the crown, is attributed to Aaron Dennison, a manufacturer responsible for numerous Waltham watch cases in the British market. The watch is equipped with a 15-jewel movement that utilizes a stem-wind and stem-set mechanism and a Breguet hairspring. The dial is white with black Roman numerals, spade-style hands, and a subsidiary seconds dial at the six o'clock position. The object is accompanied by a contemporary storage box labeled for H. Rogers, a jeweler and watchmaker based in Chichester, England. The auction description reports the watch is in working condition.

Object description

Case and Dial Design

The watch is an open-face model encased in sterling silver, measuring 49mm in diameter, excluding the crown. The case back features an intricate geometric design surrounding a central shield, which remains blank, providing a space for personal engravings or initials. The case is verified by Birmingham hallmarks dated to 1929.

The dial is finished in a matte white, accented by black Roman numeral hour markers. Time is indicated by classic black spade-style hands. A dedicated subsidiary seconds dial is located at the six o'clock position, following traditional layout conventions for pocket watches of the period.

Evidence for this section
  • “بدنه این ساعت با قطر ۴۹ میلی‌متر (بدون احتساب سرکوک) از نقره استرلینگ ساخته شده”
  • “در پشت قاب، نقوش ظریف هندسی به همراه یک سپر (شیلد) خالی تعبیه شده”
  • “صفحه ساعت به رنگ سفید مات و تمیز با اعداد رومی مشکی، نشانگر ثانیه‌شمار مجزا در موقعیت عدد شش و عقربه‌های کلاسیک مدل Spade”

Movement and Mechanism

The internal movement is a Waltham production, specifically configured with fifteen jewels set in gold jewel cups. The winding and time-setting functions are managed via the crown through a stem-wind and stem-set mechanism. The movement architecture includes plates finished with delicate decorative patterns.

Technical accuracy is supported by the inclusion of a Breguet hairspring. The movement is signed by the manufacturer, adhering to Waltham's production specifications for the market. While the auction source notes that the watch is in functional order, there is no mention of recent servicing or component repairs in the provided documentation.

Attribution and Provenance

The watch represents a cross-market product: the movement originated from the American Waltham factory, while the sterling silver case was manufactured for the British market. Aaron Dennison is identified as the case maker, a figure linked to the housing of many Waltham watches within the United Kingdom.

The provenance includes an original jewelry box from H. Rogers, located in Chichester, England. The source emphasizes that while these details are documented, the information is provided by the seller and has not undergone independent verification or authentication by the catalogue platform.

  • “نشان سازنده بدنه متعلق به آرون دنیسون (Aaron Dennison) است”
  • “اطلاعات، ابعاد و توصیفات ارائه‌شده در این شناسنامه تماماً بر پایه ادعای فروشنده و منبع اولیه گردآوری شده است”

Open research questions

  • What is the specific Waltham movement caliber number hidden by the casing?
  • Can the case serial number be traced to confirm the exact production timeline of the Aaron Dennison case?
