The combination of a date scale, day markings, small seconds and antimagnetic/shockproof inscriptions reflects the period’s focus on functionality and reliability. The design has a very charismatic vintage personality: gold-tone case, silver dial, red calendar numerals, small seconds and a busy but balanced layout. These calendar watches were created not only to tell the time, but also to offer useful daily information in an elegant mechanical format. A distinctive vintage Swiss watch for collectors who appreciate unusual calendar layouts, honest age patina and charming mid-century mechanical design. Internal Reference Number - BGT 66
