What the IW544798 Reference Is
IWC builds reference numbers from the letters IW plus four to six digits. The 5448 group dates to the 1990s. IWC does not list IW544798 on its current product pages. No manufacturer page states the dial color, case metal, or movement for that exact number. Treat any seller spec sheet as unverified. Ask for photos of the caseback engraving and the movement rotor before payment.
Pick First: First Copy IW544798 With an Automatic Movement
Pick the automatic build first. Automatic versions run a 28,800 vph movement with a 38 to 42 hour power reserve. Case diameter sits near 40 mm. Case thickness lands near 12 mm. Weight runs 90 to 110 grams on a leather strap. Price runs $180 to $350 from first copy sellers. This version holds a sweeping seconds hand and a caseback layout that matches the original reference text. Start here, then compare the rest.
Options Compared
- First copy automatic, steel case, sapphire crystal. $180 to $350. Closest match for caseback text, crown relief, and dial printing.
- Quartz first copy. $60 to $120. Ticking seconds hand. Lighter case. Date font and window cut differ from the automatic build.
- Gold plated first copy. $200 to $400. Plating wears at the lugs, crown, and buckle. Total weight stays below a solid gold case.
- Genuine used IWC 5448. Steel listings sit in the low four figures. Gold listings sit higher. A factory service adds $400 to $900.
Check Points Before Payment
- Caseback reference engraving depth and font.
- Crown logo relief and thread feel.
- Date wheel font and window cut.
- Lug width, 20 mm or 22 mm.
- Water resistance claim. Most first copy cases seal against splash contact.
- Strap hardware: buckle stamping, spring bar fit.
- Movement photos with the caseback removed.
Fit Notes
The 40 mm case fits wrists from 16 cm to 19 cm with the stock strap. Thin wrists need a shorter strap or a new hole punch. Thick wrists need a 120 mm tail length. Lug width decides which aftermarket straps fit, so confirm it before you order.
What a First Copy Cannot Do
A first copy is not a genuine IWC. It carries no manufacturer warranty. It has no IWC service history. Resale value sits near zero. Movement parts do not match IWC calibers. A watchmaker identifies the movement in minutes after opening the case. Buy a first copy for the look and the fit. Do not buy one as an investment. Budget one service every three to five years for an automatic build.
