Maintenance and Sourcing Tips
Use NOS (New Old Stock) or quality donor movements; many parts are still available from specialist suppliers and even from old stock.
Pin lever escapements need very light oiling; over-lubrication can be detrimental.
Confirm the BFG 158(CLD) identification on your movement before ordering parts or attempting repairs.
Date and calendar mechanisms are delicate—handle with care during disassembly/reassembly.
Donor movements and part kits are commonly available due to the vast historical production.
