Sellita SW500

Sellita's clone of the ETA/Valjoux 7750 automatic chronograph, used by Sinn in models like the 903 St from 2014 onwards as ETA movements became harder to source. Features the classic 6-9-12 subdial layout. Later versions (post-2020) feature an improved barrel design (RDM+) that extends power reserve from 48 to 62 hours. Also includes improved calendar setting mechanism that eliminates the traditional 8pm-2am date-change restriction of the original 7750. Available in Elabore, Top, and Chronometer grades.
