How to use this alternatives list
Start with design intent, then check market depth. A close alternative should be recognizable to the same buyer pool, have enough live or auction evidence to price, and avoid depending on a single unsold listing as proof of value.
For machine-readable output, use /api/alternatives/iwc-iw5036-05 or resolve fuzzy text through /api/alternatives/search?q=IW5036-05.
