Lot 35 and lot 23 are two-register Carreras from this same period, both with 30-minute recorders. Lot 35 has the
link SN color scheme – a silver-white dial with
link black registers. Lot 23 shows a unique style for the Carreras, with elements designed for pilots – Arabic numerals painted in lume and bright white hands with luminous
link inserts. This model was produced by Heuer for Lucht Macht – Forces Aeriennes (the Belgian Air Force), with military issuance marks on the case-back dating the watch to 1970.
