About Carter Reum’s watch collection

Carter Reum is a venture capitalist, entrepreneur, and author best known for co-founding M13, a consumer technology-focused venture fund that has backed companies including Lyft, Snapchat, and Ring. Beyond his investment career, Reum has established himself as a voice in the startup world through his book 'Shortcut Your Startup,' a practical guide to building businesses that draws on his own experience scaling and exiting companies. He is also widely recognized as the husband of media personality and businesswoman Paris Hilton, a relationship that has placed him in the public eye at major cultural and industry events.

The Carter Reum watch collection, based on our sightings, skews toward serious, purpose-built horology rather than purely decorative dress watches. At the 2021 Tribeca Festival in New York, Reum appeared on the red carpet wearing a Breitling Navitimer Montbrillant Spatiographe in stainless steel, paired with a dark brown leather strap featuring white contrast stitching. It is a deliberate choice — the Montbrillant Spatiographe is one of the more technically dense references in the Navitimer family, tracing its lineage to the 1962 Breitling Cosmonaute, the first Swiss watch ever worn in space. The 'Spatiographe' designation signals a watch built around aviation and aerospace instrument logic, not fashion cycles.

Choosing a historically grounded aviation chronograph for a film festival appearance rather than a high-jewelry or fashion-house watch says something concrete about where Reum's tastes sit. He reached for a tool watch with a documented backstory — one that rewards research — rather than a recognizable luxury logo. For a man who built a career advising founders on substance over noise, the preference for Breitling's more technical catalog rather than its more commercially visible pieces reads as entirely consistent.
