Red Star Bullhead Chronograph - Seagull movement ST19 with swan neck fine regulation.

The watch case in the 70s design is made of polished stainless steel and has the dimensions 42mm x 45mm - the length measured with the crown is 48mm.    The watch glass looks like 70íes plexiglass but is double domed mineral glass - with anti-reflective coating!    A luminous point and a tachymeter scale are attached to the bezel.    Water resistance: 5 ATM splash resistant.    The screwed crystal back - appropriately decorated with a bullhead - reveals the Seagull ST19 column wheel caliber.    This watch caliber is a mechanical column-wheel chronograph Seagull No. ST19 with manual winding, approx. 45 hours power reserve, 21,600 halfrotations per hour, shock protection and 21 jewels.  With swan neck fine adjustment.    Seagull in Tianjin bought the Venus production facilities from Switzerland in the 1960s and this special caliber is therefore identical in construction or the successor to the legendary Venus 3017 column-wheel caliber!    The blue dial - also in the 70s design - shows the stop minutes at position "12" and the seconds display at position "6" - the large red hand serves as a stop second hand.    The white minute and hour hands and indexes are luminous.
