Mido Multifort Powerwind Chronometer
- ETA 2836-2 base at a $1,500–$2,500 band retail — many enthusiasts feel the brand premium is high vs. peers with similar movement architecture in the $500–$1,000 band (Hamilton, Tissot).
- 38-hour power reserve — modest by 2026 standards where peers offer 70–80 hours.
- 50m water resistance — limited dress-sport spec; not for swimming/diving.
- 21mm lug width — awkward for aftermarket strap fitment (most aftermarket is 20mm or 22mm).
Oris Aquis Date Calibre 400
- Sellita base movement at this price — fair value but not in-house prestige (Caliber 400 variants resolve).
