I have my eye on an O&W chrono with the Valjoux 7750 movement (with my budget this is like a high end Breitling to me ).
This will be my first mechanical movement and first automatic. Is this wound by motion only (wrist or winder), or do I also have the option to hand wind with the crown on this movement?
How often do you take for oiling / service given everything is working fine?
Thanks for any info!:thanks
