In fact, I don't see chronographs. I see mostly just time-only watches. I've seen an Aquanaut 5167 on rubber strap, a Nautilus on a bracelet, multiple Rolexes, two Vacheron Constantin (on leather straps oddly), and one chef had a Panerai (don't remember if it was on a strap or a bracelet). I don't think any of them were chronographs to my recollection. In the kitchen they use plastic timers.
