Round Marble and Wood Wall Clock – Silent Quartz, 25 to 40 cm

Four sizes step up from 25 to 30, 35 and 40 centimeters, a wider range than most clocks offer and enough to make the same design workable in a small bathroom or on a large living room wall. Marble and wood share the construction, two materials that meet in almost no other object at this scale.

Marble is stone and behaves like it: heavy for its size, cold to the touch, and porous enough to take up a mark from anything oily left against it. On a clock that porosity matters mainly at the edges, where hands make contact during hanging. The weight matters more, because marble at 40 centimeters is a genuinely heavy object to put on a wall and the fixing needs to reach something solid rather than plasterboard alone.

A stone-faced clock suits a bathroom or a kitchen where hard surfaces are already the norm. The smallest size works where a 40-centimeter piece would be both too large and too heavy.
