An IWC replica IW371653 is a copy of the Portugieser Chronograph from the 3716 family: a 41 mm stainless steel watch with leaf hands, applied Arabic numerals and two subdials set at 12 and 6. The genuine model runs IWC's manufactured caliber 69355, so every replica substitutes an Asian automatic chronograph movement. The gap between a cheap copy and a high-grade one shows up in dial printing, subdial depth, case finishing and how the chronograph starts, stops and resets.
What should a replica IW371653 match on the real watch?
The 3716-generation Portugieser Chronograph sets proportions that a good copy has to follow closely.
Replica IW371653 vs Original: Portugieser Chronograph Compared
- Case: 41 mm stainless steel, about 13 mm thick, roughly 20 mm lug width.
- Dial: two-register layout with a 30-minute counter at 12 and running seconds at 6, applied numerals and leaf hands.
- Crystal: domed sapphire with anti-reflective coating.
- Movement: caliber 69355, automatic, 28,800 vph, about 46 hours of power reserve.
- Strap: alligator with a steel pin or folding clasp, and light water resistance on the case.
Reference numbers inside the 3716 family differ by dial color, hand finish and strap, so confirm which dial the IW371653 designation covers before you compare photos.

Finishing quality shows first at arm's length, then under a loupe.
Best Replica IW371653: My First Pick, Then the Alternatives
- Printed scales and numerals: crisp edges with no bleed or fuzzy outlines.
- Subdial rings: cut into the dial with a slight recess, not flat stickers.
- Hands: leaf shape with a visible polished bevel along the center ridge.
- Case: brushed flanks with straight, even graining and a clean polished bezel transition.
- Pushers: a firm click on start and a snap back to zero on reset without stutter.
- Crystal: clear sapphire with a faint blue or purple AR tint, not cloudy mineral glass.
- Date window, if the reference carries one: square cut with a font that matches the numerals.
- Caseback: engraving with enough depth to survive a fingernail test.
Which movement powers a replica IW371653?
IWC does not sell the 69355 as a loose calibre, so replicas rely on Asian chronograph movements. Most mid-tier copies use a 7750 derivative adapted to a two-register layout, while higher tiers use newer custom bicompax calibers with a smoother pusher feel. Ask whether both subdials actually work, since some budget copies leave the 12 o'clock counter decorative.
Expect around 40 hours of power reserve, 28,800 vph and daily accuracy near 10 to 20 seconds after regulation.
How much does a replica IW371653 cost?
- Entry tier, about $120 to $220: quartz or basic automatic movement, flat dial printing, mineral glass.
- Mid tier, about $250 to $400: 7750-based automatic, sapphire crystal, solid case finishing.
- Top tier, about $450 to $700: custom bicompax movement, tighter dial detail, better strap and clasp.
Price tracks movement, dial work and case finishing. A high price alone does not guarantee those details, so compare photos rather than listing text.
What should you check before buying?
- Request photos of the dial at an angle, the caseback and the movement with the rotor turned.
- Ask for a timegrapher reading with rate and amplitude.
- Watch a short video of the chronograph starting and resetting.
- Confirm strap material, clasp type and lug width.
- Treat water resistance claims as optimistic and keep the watch away from water.
