Co do In-house, to może faktycznie zbyt szumnie powiedziane. Powinno być "In-house". Ciekawostką jest natomiast to, że bazowy mechanizm, który poddawany jest obróbce, choć taki sam jak 2824-2, nie pochodzi z ETY, ale od małej niezależnej firmy w Szwajcarii. Gunter pisał po tym na Watchuseek: As many here have guessed already, the new ST.5 is the same basic construction as the ETA 2824, making it an efficient workhorse for a selection of our automatics. The important part is, that it's Swiss Made and that the components for it are sourced from Swiss manufacturers that are not owned by any large holding company, making it an independent option for STEINHART. It has been tried and tested extensively and promises to be a very reliable and precise engine. The ST.5 will not replace the ETA 2824-2, we will continue to gladly work with ETA for as long as possible. But like the 2824, the ST.5, although decorated, will not be observable through an exhibition case back. Co do prawdziwych In-House, to poniżej informacja, kto obecnie je robi, do tego nie są one robione w 100% z części własnych: The most famous Swiss brand that produces their own watch movements is Rolex. While Rolex does not produce extremely complicated movements, they are considered to be very well-made, and Rolex certainly produces a large number of them. Still large in production but way under Rolex numbers you have brands like Patek Philippe, Jaeger-LeCoultre, Blancpain, Piaget, A. Lange & Sohne, Zenith, and Audemars Piguet (among others) who produce in-house made mechanical movements for most all of their products. Pozostaje zaproś do ich butików
