Thanks for sharing your experience with the new 3861. I like that this is a forum where folks share their points of view, and in general it's a fairly friendly place with moderators who don't tolerate the sort of stuff seen on the other forums most of us also frequent.
I've owned the sapphire 3861 for one week. I'm not planning on selling it. Let me share why that's the case in light of your comments.
1. I seldom flip watches and usually have an emotional connection to each purchase. Sure, I've sold a white Mark XV and an Ingenieur due to both requiring warranty service and a lack of responsiveness from Richemont. I also unloaded a WG Saxonia after 7y, deciding that having it and a similar dress watch were more than I wanted to own. There's also that used Sinn 856 that I had for like a month. The only flipping regret? Selling my first ST1.
2. It's exciting to have the first fundamentally new Moonwatch since the 861s started production. It was thrilling seeing the early news late last year, and then hoping for a big splash on the first SpeedyTuesday of the month, which actually happened! Coupling that with my awesome SA at the local OB reaching out and learning I could get one of the first watches in the US is a lot of fun, too. -Don't think I've ever done that before, getting a watch at its launch!
3. This watch comes at a very historically significant moment and will forever be tied to going through the heaviness of the COVID-19 pandemic and then the recent disastrous political events of last week. In other words, it's something that is full of optimism and hope, compared to what we've all been suffering through lately.
4. It was of some risk to get the watch, as the case rates are still crappy and there's the more virulent strain out there. Never have I been in such a hurry to get out of the OB! That's something I'll remember, too, having to brave COVID-19 to pick up a time piece. Needing to be given black rubber gloves so I could touch a Snoopy they had (not for sale!?).
5. I am happy with the METAS rating, the stepped dial, display back (esp. the font), bracelet size, pushers, style, and fit. So, I'm fortunate that it works for me. I'll probably put it on the Omega velcro strap at some point. I currently wear my 1861 hesalite more though as it's been beaten up a lot and I worry less about bashing it as a clumsy left-handed boomer.
6. I'm very happy with Omega as a brand and Moonwatches as a watch. I connect closely to that history. I've no love for Rolex these days, in spite of having a 16710 that has been in my possession since I bought it in 1997. Their current sales model doesn't work for me at many levels, which is now where we are with PP and AP, too.
So, yeah, most of this reply is not about the watch directly, but I am really happy with the watch. Really!
Thanks again for sharing!
