Jan Lot 79- Elgin O Size & 12 Size Blued Factory Packaged Mainsprings

These are four (4) blued O size factory package pocket watch mainsprings and 7 blued 12 size pocket watch mainsprings These springs are very expensive when purchased one at a time from a horological material house. Just the use of a single spring can save a future repair. This is a very good opportunity to stock up your Elgin pocket watch and lapel watch blued mainsprings at a fraction of the cost of purchasing them one spring at a time from a horological material house.
