Mercer – 14,040.

An untouched early 20th century two-day marine chronometer with a 24-hour dial made by Mercer and retailed by H. Hughes and Sons, Ltd.

The tiered flame mahogany case has campaign style handles and the retailer’s label on the front, ‘ H. Hughes and Sons, Ltd, 2105,14040, London’

The engraved slivered 24-hour dial has the hours and minutes’ chapters with Arabic numbers, a small up/down 56-hour dial, a second’s dial and is signed ‘H.Hughes &. Sons, Ltd., 59 Fenchurch St,  London, 2105 14040’ , has steel-cut hands and is engraved ‘Auxiliary Compensation’ in red.

The 2-day fusee movement is housed in a gimballed tub, has beautifully spotted plates, maintaining power, a detent escapement with a bimetallic balance with Poole’s auxiliary compensation and a Palladium balance spring.

Henry Hughes & Sons were at 59 Fenchurch St from 1868-1941, and thereafter became Kelvin Hughes.

The chronometer was made by Mercer, hence the fractional number on the dial; 2105 is the Hughes number, 14040 the Mercer movement.

It is in untouched unrestored condition.

Case key labeled with a Sotheby’s tag.
