Konstantin Chaykin · Seneca II

Strengths

The strongest idea is a calendar that contributes to the character instead of merely adding a date.

Things to consider

A unique piece: availability and pricing cannot be treated like those of a serial model.

Konstantin Chaykin — Seneca II

Oris · Big Crown Pointer Date Oxblood

Strengths

A strong choice of design for someone who wants a familiar watch with a visible, well-organised calendar.

Things to consider

41 hours is not a long-weekend reserve without additional winding.
