Your home or office may not be a hazardous environment, but that shouldn’t stop you from hanging a vintage explosion-proof clock ($1,200) from the Crouse-Hinds Company on your wall. Designed with heavily insulated components to make it safe for use in volatile environments such as mines, paint factories, and grain processing plants, this 40-pound clock from the 1950s is like a G-Shock for your wall. It’s nice to know your clock will keep on ticking even if, heaven forbid, you aren’t around to need it. This one’s available from the fine folks at Modern Fifty, an interior design collective.
