For sale is a **Serica 5303-3 COSC ("crystal blue"),** dated to 5/2023. It's in excellent condition and has been worn very carefully, with only a few very faint hairlines. The crystal and bezel are in perfect condition and in general lighting the watch looks 9/10 new. It's keeping very good time. I find the bezel to be slightly stiff but this may be a quirk of the model.  Comes with all original boxes, tags, and COSC certificate. **Asking \[SOLD!\] OBO shipped anywhere in the U.S.** I take Zelle or Venmo (sorry, no PayPal) or Cash if you're willing to meet in Chicagoland. Not interested in trades. I've sold many watches here, including two 2024 Rolexes, a 2023 Speedmaster, Cartier Tank, Tudor Black Bay 54, etc. I'm happy to have a video call or other forms of confirmation with you. Buy with confidence! **Full album with more photos** at: [https://imgur.com/a/ota9d6d](https://imgur.com/a/ota9d6d)
