https://www.spiralwinderwatchparts....ety-tachymetre-bezel-for-the-3861-speedmaster Note: I’m not affiliated with this company in any way, I just thought this was cool and wanted to share. Mods, feel free to remove if needed. Just found out about these and am curious to hear your thoughts. Looks awesome, should be more scratch-resistant, and easily reversible for when you need a service. Price feels a little steep so I'll probably wait to find one secondhand. I'm sure Moonwatch purists will disagree but I'd absolutely love for Omega to do a ceramic/lumed bezel like this on the next generation of the sapphire model Speedy Pro.
