Has to be either a new hairspring or a new mainspring right? 3861 already has the SI14 hairspring afaik
Yes it’s one or other, looks more like a mainspring maybe. Rolex can do 70 hours reserve on a single mainspring, I think the best Omega can offer is 60hrs on their double spring movements like the 8900 and 9300 (and only 55 max on a single spring) so there is scope for improvement there. Maybe they've found some new alloy that allows a lot more reserve. Let's hope it isn't some elctromechanical dead end like Seiko kinetic or similar. Last time Omega did that it didn't really catch on.
On the mainspring front they can potentially do a lot more than 70 hours if they really want to as Omega has Blancpain as a stablemate within Swatch group and borrows expertise, movements and tech from them when needed as they did with the recent Chrono Chime.
Blancpain is currently getting 288 hours out of a single barrel on their Villaret tourbillon so that’s a pretty high ceiling if they want to push the envelope.
Surely gotta be more than a silicon hairspring that doubles the running time between winds on a Speedmaster.
But on retrospect it will justify the $600 price rise coming
How big is that barrel though? You could go for weeks if you had enough space presumably. Maybe the advance is in miniaturisation of whatever special sauce that one uses.
New silicon hair spring for the Speedmaster Pro?
