I'd go for a cheap, temporary replacement hoping that the original turns up. The one thing I've learnt about lost items is that they tend turn up the minute you buy a new one!

Maine coons are notorious for that behavior but sometimes it can be dangerous to them (they have been known to swallow things they shouldn't). I'd probably give it a bit more time and so a little more looking. Maybe you could set up a nanny cam to see where the little one likes to hide things?

The breeder forgot to mention this behavior! It has, however, made DD1 really good about picking up her toys! I now put my other watch and any jewelry in the drawer of my nightstand.

He's so good with the kids it's amazing. And he's enormous. At 5 months, he's bigger than my Russian Blue. We sometimes forget he's still a kitten! They are both indoor only kitties, so it has to be here. But there are so many nooks and crannies, and we're worried he might have hidden it in our very messy basement. . .

I think I am going to start hunting for a new gold watch to love. I now know it's worth the splurge as I wear it all the time. If the other turns up in a few months, I will just have 3.

I always seem to find the thing I was looking for as soon as I buy a replacement, so I'm in the "buy a different watch" camp. Not necessarily a cheap one but not a duplicate, either.

Even though I'm a smart phone addict I still wear a watch most of the time. It's a pain to have to dig out my phone and unlock it just to see what time it is when I could just glance at my arm!

I like Diana's suggestion of same company but different ( doesn't have to be wildly different!) style. That way you're buying something you love that you know works for you and if the lost one turns up you won't feel silly.
I'd rather go without than buy something I don't like as much because it's cheaper.
I had no idea cats did things like that. I'm really more of a dog person but this story makes me think I underestimated cats.

That's one c-r-a-z-y cat! I can think of good reasons for following any one of your possible courses of action, but to find the Movado, I second Joy about calling on St. Anthony--he's NEVER failed me (and I've misplaced a lot of things.) A friend from Chicago told me years ago to chant, "Saint Anthony, Saint Anthony, please look around. Something is lost that must be found" several times, then be quiet. It's amazing how often the solution pops into my head, like the answer in a Magic 8 Ball. Meanwhile, watch your kitten play: does she bat things sideways? If so, you'll most likely find the watch on the floor, caught behind a furniture leg, upholstery, etc. Good luck!
