The Benrus Watch Company was founded in New York City in 1921 by three Romanian immigrant brothers: Benjamin, Ralph, and Oscar Lazrus. The company's name was a portmanteau of Benjamin's first and last names. By adopting a business model that imported reliable Swiss ebauche movements (primarily from ETA) and casing them in American-made, design-forward enclosures, Benrus quickly grew to become one of the most prominent mid-century American watch brands alongside Hamilton and Bulova. During the optimistic post-WWII era, Benrus capitalized on the demand for sophisticated, professional-grade wristwatches. Their Day-Date Pointer models were highly popular, offering complex horological functions—like the signature red-tipped calendar pointer hand and a day aperture—at an accessible price point. While the brand eventually succumbed to the Quartz Crisis in the late 1970s, their mid-century mechanical complicated watches remain highly respected by vintage collectors today for their quintessential Art Deco and Mid-Century Modern aesthetic.

Valuation for this model is strictly bifurcated by mechanical health and originality. Accepted comparable sales indicate that running, watch-only examples with honest aging routinely sell between $200 and $300 on peer-to-peer and auction platforms. Fully serviced pieces with restored dials from specialist dealers establish a strict ceiling around $450 to $500, but these retail prices are not reflective of raw auction hammer values. Conversely, non-running project pieces plummet to the $75 to $100 range due to the scarcity of replacement calendar jumper springs for the vintage CE-13 movement. Given the unknown mechanical service history of the subject watch, the estimate spans from a strong unserviced tier to a healthy running mid-market valuation.
