TMZ reports someone got into Scott's mansion in the Hidden Hills section of Los Angeles and took "multiples worth a significant amount of money" from his watch collection, which also includes a $48,000 timepiece. Police have not reported how many or which specific watches were stolen.
Police reportedly think it was "inside job," as there was no sign of forced entry into the home where Scott regularly hosts parties.
When the theft occurred last week, Scott was in France, where he partied with his rumored girlfriend, Christine Burke, as well as Kendall Jenner, Kris Jenner and Tyga at clubs during the Cannes Film Festival.
(Earlier this month, Rob Kardashian's fiancee, Blac Chyna, experienced a similar ordeal when $200,000 in cash and a slew of jewelry went MIA from her home without any signs of a break-in.)
The stolen watches aren't the only bad news following Scott around these days.
A source recently told Us Weekly that Scott's "been sick for a while and his drinking is making it worse."
The father of three, who split from Kourtney Kardashian last year, has been in and out of rehab for years, the most recent stint having kicked off last fall.
He also made headlines last week for accidentally cutting and pasting the instructions he'd obviously gotten from an Instagram sponsor in the post he was clearly being paid for.
"Here you go, at 4pm est, write the below. Caption: Keeping up with the summer workout routine with my morning @booteauk protein shake!" Scott wrote before deleting and rewriting it.
As for the watches, some outlets have implied Scott's been overly open about his collection.
"If the day is professional ... a Patek Philippe," he told Haute Living in 2013. "If my day seems more relaxed I will just wear a Rolex. If I know I have an event to go to and I want to be a little flashy I will wear one of my completely flawless diamond Jacob and Co. watches."
