The 30CH caliber was equipped on watches with more sporty design if compared to the previous one, following the trends and demands of the post Second World War society. The request of solid cases reliable and with a good aesthetic taste led Longines to create some very sophisticated and dressy versions of wristwatches such as the present one. Very nice representative of the reference 23 505, it is also called by collectors Cornes de Vache for the unusual and iconic shape of the lugs. Manufactured in stainless steel, the three body case has a rounded bezel, snap-on case back and preserved in very nice conditions. The matte silver dial has applied steel triangle and Arabic indexes, subsidiary dials for the seconds and the 30-minute register, outer 1/5th of a second/minute track, red telemeter scale and outermost blue tachometer scale.
