I contacted Stowa to see if they could remove the blue insert from a pre-owned stainless bezel and install it on a titanium bezel. I figured it was a long shot, but I received the following response from Nina:
"I talked to my colleague and I have good news for you because we have one blue bezel. So if you are interested in you can send me an email and I can order the watch for you with the blued bezel."
I no longer had an excuse to hold off on the Seatime! Hopefully it'll arrive in 4 weeks (or sooner)! I'd still like to order a spare blue bezel, though! Eventually I'll order the green, red/orange, and black!
