If you’re in Tokyo and you’re into watches, visiting the Seiko Museum is a no-brainer. It’s not particularly large, but it’s free, and it’s quite interesting.
Seiko has a long and storied history — they’ve been around since the late 1800s, first as a manufacturer of wall clocks, and then, of course, watches.
There’s a lot of interesting watches on display in the museum: the first Seiko wristwatch, the first quartz watch ever, the first Grand Seiko, etc.
If this sort of thing doesn’t interest you, then this small, no-frills museum certainly isn’t going to change your mind. While I was there, a guy came in with a young kid, and I think they hung around for about five minutes. Meanwhile, I lingered for closer to 40.
Location: 3 Chome-9-７ Higashimukōjima, Sumida-ku, Tōkyō-to 131-0032
