Available at last!  A durable and precision-made battery spacer that allows the use of 357-size cells in LED watches that originally used the now-unavailable 355s.  Individually machined from solid Delrin bar (not an O-ring, 3-D printed, or cheap piece of plastic tubing!), and tested for fit before shipping.  Black color blends into and maintains the original look of the module.  A must-have accessory for the serious collector or owner; loose cells in the battery compartments can short out and damage the module.  Spacers pictured fit all Pulsar P1, P2 & P3, Hamilton QED & QTC, and Omega TC1 & TC2 models.  All my vintage P1, P2 and P3 Pulsars are fitted with these (the Hamiltons and Omegas, too); they have become the "gold standard" for battery spacers!  Also included is a pair of the best batteries made anywhere (Renata silver-oxide 357).      PLEASE NOTE: the module pictured is NOT included; it is shown solely to demonstrate how the spacers fit and look when installed.   ALSO:  Price for international shipping has increased drastically in the last year.  I charge only ACTUAL shipping cost; sorry, but it is a factor beyond my control (typically $17-25).  Recent increases in the price of silver has also raised the cost of batteries.
