- Buyers who prefer a commanding wrist presence — 43mm case
Mido Multifort Powerwind Chronometer
- ETA 2836-2 base at $1,650 retail — many enthusiasts feel the brand premium is high vs. peers with similar movement architecture (Hamilton at $575, Tissot at $725).
- 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 $2,300 — fair value but not in-house prestige (Caliber 400 variants resolve).
- 43.5mm large for smaller wrists (smaller variants available).
- Proprietary endlinks limit strap options.
