Ticking within we find what Bremont calls the BE-36AE movement, which starts out as an ETA 2836
link but has been modified for its no-date application (no
link phantom date position) and then
link further bolstered for additional shock resistance. With a rate of 4Hz, it offers an ETA-standard 38 hours of power reserve and has been chronometer-certified by Bremont to the ISO 3159 standard.
