At an overall diameter of \u003cstrong\u003e24 inches\u003c\/strong\u003e, this is a commanding object; the dial alone spans 18 inches across.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003eSynchronome\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe Synchronome Electric Company\u003c\/strong\u003e was founded in London in 1895 by Frank Hope-Jones, a figure central to the development of precision electrical timekeeping in Britain. Where other manufacturers produced clock systems for the institutional mass market, Synchronome built instruments of genuine technical distinction — their free-pendulum master clocks are among the most accurate mechanical timekeepers ever made, and their slave clock systems, driven by precisely timed electrical impulses from those master movements, set the standard for precision time distribution in British industry, science and public life throughout the early and mid twentieth century. A Synchronome on the wall of a factory, laboratory or institution was a mark of quality that went beyond the utilitarian — a statement that accurate time mattered to the people working there.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003eThe Clock\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003eThe case is a \u003cstrong\u003esubstantial cast iron double-ring bezel construction\u003c\/strong\u003e — a stepped profile quite distinct from the single drum format used by most factory clock producers, the outer ring and inner bezel casting a deep shadow against the dial face that gives the piece an architectural quality in person. The finish is the characteristic \u003cstrong\u003einstitutional green\u003c\/strong\u003e, original and largely intact with the honest surface variation of a long working life. A \u003cstrong\u003esingle cast hanging bracket\u003c\/strong\u003e sits at the twelve o’clock position, original to the case, with a central fixing hole — this clock was hung from a single point, the format used where a ceiling bracket or wall plate carried the weight. Fixing holes are present around the outer perimeter of the bezel.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe dial is \u003cstrong\u003ecream painted metal\u003c\/strong\u003e, carrying a face of \u003cstrong\u003ebold Roman numerals\u003c\/strong\u003e in the classic Synchronome serif format — tall, clean, authoritative type of the kind that reads from across a large working floor. The inner minute track runs in a fine arrangement of alternating dash and tick markers around the perimeter. In the centre of the dial the \u003cstrong\u003eSYNCHRONOME name\u003c\/strong\u003e is printed in a confident uppercase serif face, with \u003cstrong\u003eLONDON\u003c\/strong\u003e below and the reference number \u003cstrong\u003e14\u003c\/strong\u003e directly beneath the hand pivot — a production or batch number that adds a further layer of provenance to the piece.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe surface of the dial has developed a \u003cstrong\u003eremarkable natural oxidation\u003c\/strong\u003e — large warm islands of amber and ochre lifted from the cream ground, with darker areas of original paint loss where the face has been exposed over decades. The result is a dial of extraordinary visual character: part map, part abstract painting, entirely unrepeatable. It is not damage — it is the record of the clock’s life, and it is one of the most compelling dial surfaces in this current run of pieces.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe \u003cstrong\u003ehands are original and complete\u003c\/strong\u003e — a broad spade or tulip-form hour hand and a long tapered minute hand, both fitted with a small rounded counterbalance lobe at the tail, in blued or black steel. The hand form is quite different from the arrow style used by Gent, and immediately identifies this as a Synchronome product.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003ePower\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003eAs a slave clock, this piece is \u003cstrong\u003eoffered for display or conversion\u003c\/strong\u003e to independent battery or mains operation with a suitable replacement movement.
