Overview
This is a classic brass-cased desk clock from Tiffany & Co.'s celebrated 'Portfolio' collection. Designed with architectural columns flanking a clean, white Roman numeral dial, it updates the traditional 19th-century carriage clock for the modern executive desk.
Story
In the 1980s, Tiffany & Co. launched the 'Portfolio' line to bring their legendary luxury to daily business life. This clock sat on the desks of high-flying executives during an era of power suits and Wall Street booms.
Maker / Origin
Founded in New York in 1837, Tiffany & Co. evolved from a 'fancy goods' store into an arbiter of global taste. Their horological history is prestigious; they partnered with Patek Philippe in 1851 and have produced some of the world's most coveted timepieces.
Condition & Value
The brass case shows minor surface dust and light oxidation consistent with age. The crystal appears clear, but the movement must be tested with a fresh battery to ensure no internal acid damage from old batteries. Working condition is paramount to reaching the higher end of the value range.
