The way you get it in 35 seconds for Ukranian job is if, and this is incredibly unlikely, the tiara isn't in a safe and is on display in the front. The odds are ridiculously low, but it's literally a walk in, break glass, grab, walk out affair.
Since I don't have pick safes, I'm usually brute forcing the job when I take it. 5 minutes approximately how long it takes, cause you're a pseudo tank with your dodge rate as ghost, so you can run out the side alleys and make it with about quarter health damaged.
