In terms of technical specifications, the SPB439 is powered by the manual-winding and automatic 6R54 caliber, which provides a power reserve of 72 hours. The caseback of the watch features an engraved emblem and a unique batch number. The timepiece is completed with a stainless steel Oyster style bracelet.
