Domestic Regulator Longcase Clock by John Barwise

Partially verified

This antique longcase clock is identified as a domestic regulator clock with an eight-day movement, attributed to the London-based clockmaker John Barwise, circa 1800. The case is constructed from mahogany and features flame veneers on the trunk, a shallow arched hood, and reeded chamfered corners flanking the hood door. It stands on a shaped plinth base. The regulator-style dial includes a separate hour indicator, an outer minute track, and a subsidiary seconds dial, signed «Jn Barwise LONDON». Technical components include a high-quality movement equipped with a dead-beat escapement and a maintaining power mechanism, intended to ensure continuous operation during winding. While the source describes the aesthetic and technical attributes of the object, it does not provide details regarding the current state of preservation, specific provenance, or the precise physical dimensions of the timepiece.

Object description

Case Construction

The clock is housed in a mahogany case decorated with flame veneers on the trunk. The design utilizes a shallow arched hood to cover the dial, which is flanked by reeded chamfered corners. The ensemble is supported by a shaped plinth base.

The overall aesthetic is defined by the wood grain and the architectural proportions of the hood and base.

Evidence for this section
  • “بدنه ساعت از چوب ماهون (Mahogany) ساخته شده و دارای روکش‌های طرح شعله‌ای بسیار زیبا (Flame Veneers) روی تنه ساعت است.”
  • “کلاهک ساعت دارای طاق کم‌عمق (Shallow Arched Hood) است و در دو طرف درِ هماهنگ کلاهک، گوشه‌های پخ‌خورده با شیارکاری (Reeded Chamfered Corners) دیده می‌شود.”
  • “بخش پایه ساعت نیز روی یک سکوی فرم‌دار (Shaped Plinth) مستقر شده است.”

Dial and Timekeeping

The dial layout follows the regulator standard, featuring a separate hour indicator, an outer minute ring, and a subsidiary seconds hand. The dial is signed "Jn Barwise LONDON," identifying the work of the London-based clockmaker.

Technically, the clock is specified as an eight-day regulator. The movement incorporates a dead-beat escapement and a maintaining power system, which allows the clock to continue functioning while being wound.

Evidence for this section
  • “صفحه ساعت از چیدمان کلاسیک رگولاتور (Regulator Dial Layout) پیروی می‌کند”
  • “صفحه ساعت دارای امضای «Jn Barwise LONDON» بوده”
  • “موتور ساعت دارای کیفیت ساخت بالایی بوده و به سیستم رقاصک با چرخ‌دنگ ددبیت (Dead-beat Escapement) و مکانیزم توان ممتد یا نیروی نگهدارنده (Maintaining Power) مجهز است.”

Reported Condition

The source does not provide specific data regarding the operational health or recent service history of the movement. Collectors are advised to verify the functional integrity of the escapement, pendulum, and weights.

There is also a recommendation to examine the internal components for integrity and to confirm the originality of the external hardware, including locks and surface finishes.

Evidence for this section
