Brand new from Jomashop, a grey-market (non-authorized) dealer, so expect the store's warranty (Jomashop lists '2 Year Jomashop Warranty') rather than the brand's. Also checked: WatchMaxx $4,350 (10:29 PM ET). 'List' is the retail figure the dealer displays; I could not confirm it on the brand's own US site. Prices change fast; check the store before you buy.

Which one I'd pick
Which one: I priced IW356517. IW356502 (black dial, leather) was listed at the same $5,400 list at Jomashop.
What to check before you buy
- Warranty: grey-market new watches usually carry the dealer's warranty, not the brand's. Ask which one you get and whether the brand's warranty card is included.
- Exact reference: dial colour, size and strap change the price. Match the full ref (IW356517) before comparing deals.
- Fakes and red flags: be wary of prices far below the ranges above, stock photos only, or sellers who won't show the caseback, serial and papers.
