So, I’ve been on this whole watch thing lately, yeah? It started out innocently enough – just admiring them from afar, you know? But then I got this crazy idea to measure the thickness of my favorite watch, the Rolex Datejust 36. I mean, it’s not every day you think about how thick your watch is, right? But there I was, ruler in hand, feeling like some kind of watch detective.

First off, I grabbed my trusty old ruler – the one I’ve had since, like, grade school. I figured, “How hard can it be?” Turns out, measuring a watch with a regular ruler is like trying to thread a needle with boxing gloves. It’s just not made for that kind of precision. Plus, I didn’t want to scratch my precious Datejust. That’s a big no-no.
Then, I remembered this little thing called a “caliper” that my grandpa used to use. He was a total DIY guy, always tinkering with stuff. I rummaged through his old toolbox – it was like stepping back in time, seriously – and found one. It looked complicated, but after fiddling with it and watching a couple of YouTube videos, I got the hang of it. It’s this nifty tool that lets you measure things super accurately. This tool has two arms that close on the measured object.
Measuring the watch was a whole different ball game with the caliper. I carefully placed the Datejust between the jaws of the caliper, making sure not to squeeze too hard. I wanted the thickness of the case, not including that little knob on the side – you know, the crown. I read somewhere that it doesn’t count. The number I got was way more precise than what I could ever get with my old ruler. It’s amazing how different tools can change the game. I saw this number that I never knew what it means, I knew that it shows the thickness but I had to be sure.
- I went online, browsed a lot, and started digging around.
- I found this website with a calculator, not just a normal one, but one that solves math problems.
- I typed in some basic arithmetic stuff, just to test it out, and bam – it gave me the answers, no problem.
But here’s where it got a bit tricky. I had this number from the caliper, but I wasn’t sure if it was in millimeters, inches, or what. So, I started experimenting with different units in the calculator, you know, trying to make sense of it all. I felt like a real scientist, honestly, with my watch, my caliper, and this online calculator. I used a division symbol to see the ratio, I added and subtracted numbers, like a child.
After a bunch of trial and error, and a few “aha!” moments, I finally figured it out. The thickness of my Datejust 36 was right there, in millimeters, clear as day. I compared it to the official specs online, and what do you know – I was spot on! It was such a satisfying feeling, like I had cracked some secret code or something.

This whole experience taught me a lot. Not just about watch thickness, but about patience, using the right tools, and the power of online calculators. Who knew measuring a watch could be such an adventure? It’s funny how one little thing can lead you down a rabbit hole of learning and discovery. And now, every time I look at my Datejust, I have this little secret knowledge about it, a story to tell. It’s more than just a watch now; it’s a reminder of that time I turned into a watch-measuring detective.
