Short answer: a fake IW329075 is either a tier-one build that copies the case and dial closely enough to pass at arm's length, or a budget copy that fails the moment you wind it. The top pick for most buyers is a tier-one replica from a seller who posts macro photos of the dial, crown, case back, and movement, because those four images answer almost every question. The criteria that decide quality are case geometry, dial and hand finishing, movement behaviour, and documentation. Everything below works whether you are grading a replica or trying to catch one being sold as genuine.

Start with the reference, not the photos

Before you compare anything, confirm what IW329075 is meant to be. Case size, dial variant, crystal shape, and movement family all come from the reference itself, and the fastest way to confirm them is the maker's own catalogue rather than a reseller caption. A large share of bad listings fall apart here: the seller quotes a case diameter that does not match the reference, or shows a dial colour that was never produced for it. Treat every mismatch in the listing text as a warning about the watch in the box.

Criterion 1: Case geometry and finish

  • Correct lug width and case thickness relative to the genuine piece
  • Brushing direction and grain matched to the original
  • Crown diameter, knurling, and thread pitch that feel solid when screwed down
  • Weight close to steel, with no hollow feeling through the lugs
  • Case too thick, usually by a visible margin in side photos
  • Polished chamfers cut too wide or too bright
  • Crown sitting proud of the case with a wobble when you turn it
  • Sharp lug edges and spring bar holes drilled off centre

Use case: if you wear the watch daily and people see it from a metre away, grade the case first. A fraction of a millimetre in thickness disappears on the wrist; a crown that rattles and a bezel that catches light the wrong way does not.

Criterion 2: Dial, hands, and printing

  • Indexes applied straight, with even spacing at 12 and 6
  • Text weight and spacing that stays crisp under magnification
  • Date font and window position matching the reference
  • Lume colour that reads creamy rather than neon under indoor light
  • Soft or fuzzy printing that smears at 10x
  • An index leaning off the vertical axis, most obvious at 12
  • Hands too thick or too thin, with rough edges on the sword tips
  • Dust or debris caught under the crystal, a common budget-tier problem

Use case: this is the criterion that decides whether a replica reads as convincing on a video call or across a table. Ask for a straight-on dial photo and a raking-light photo, because the raking shot exposes printing and lume faults the flat shot hides.

Criterion 3: Movement and winding feel

  • Smooth hand winding with no gritty spots through the full range
  • A rotor that turns quietly and settles without rattling
  • Power reserve close to what the seller claims
  • Timekeeping stable across a week of normal wear
  • Gritty or notchy winding, a sign of poor finishing and thin lubrication
  • Rotor noise audible from a foot away
  • Engraving that copies a calibre name but not the layout of the plates
  • Rate that drifts by more than a handful of seconds a day

Use case: buyers who plan to keep the watch for years should weight this criterion above cosmetics. Ask the seller for a short video of the winding action and the rotor spin before payment. Do not open a case back yourself unless you accept the moisture and dust risk.

Criterion 4: Documentation and serials

  • Sellers who state the tier plainly instead of implying authenticity
  • Case back and movement numbers that agree with each other
  • Honest disclosure of what is included: box, card, manual, or watch only
  • Papers presented as genuine without a checkable service or dealer trail
  • Serial stamps that are shallow, uneven, or in the wrong font
  • A price far below the market for a genuine example of the reference
  • Reluctance to supply extra angles or a timed video

Buying checklist

  1. Confirm the reference details against the maker's own listing.
  2. Request macro photos of the dial, crown, case back, and clasp or buckle.
  3. Request a video of the winding and rotor movement.
  4. Compare stated dimensions against the reference specification.
  5. Decide the tier you are paying for, and confirm the seller agrees in writing.
  6. Remember that selling a replica as genuine is illegal in the US, and counterfeit shipments can be seized at import.

Which route fits you

If certainty matters more than price, buy a genuine example and have it checked by an authorised service centre, since counterfeit goods are routinely refused for service. If you want the look and accept the trade, a tier-one replica from a seller who shows movement footage is the practical choice, with the movement itself the reliable giveaway. If the budget only reaches the cheapest tier, skip it: the case and dial faults will show up within a week, and the money is better saved toward a better build.
