Braun - Calculator - 1970-1980

Iconic vintage solar pocket calculator from Braun, embodying the celebrated design philosophy of Dieter Rams and the Braun Design Team.
The Control Solar ETS 77 (Type 4777) is a refined piece of late 1980s German industrial design — clean lines, restrained geometry, and a perfect balance between form and function. The combination of charcoal-grey housing, subtly recessed solar cell, LCD display and signature coloured keys (green for functions, brown for memory, yellow accent on the equal key) makes this calculator instantly recognisable as part of Braun's design heritage.
This model is part of the lineage of Braun calculators that have become true design icons, directly inspiring the visual language of Apple's iOS Calculator app.
