The Reference 5441 was a limited addition from 1993 to celebrate IWC’s 125th anniversary. There were 250 platinum, 500 rose gold and 1000 stainless steel versions made. The first 100 platinum versions came in a special collectors‘ edition consisting of three watches in all three metals. Here are the specs:
  • Case Diameter: 42 mm
  • Case Thickness: 9.8mm
  • Movement: Manual-wind IWC Caliber 9828 (pocket watch movement)
  • Power Reserve: Approximately 54 hours
  • Dial: Silver or white with applied gold Arabic numerals, leaf hands, small seconds subdial at 6 o'clock
  • Crystal: Plexiglass (acrylic) for the front (vintage style), sapphire display back
  • Water Resistance: 30 meters (3 ATM)
I owned the stainless version originally and liked it so much that around ten years ago, I had the opportunity to purchase the collectors’ set in all three metals, new in the box, from Germany. I had IWC fully service them before having them shipped to me as they were then over 20 years old. 

In reviewing Emmanuel’s recent wonderful post about the Grand Seiko reissues of the First Grand Seiko from 1960, the classic good looks of all those reissues strongly reminded me of the same classic looks of the 5441, which I haven’t taken out of the safe in quite a long a while.

I am wearing the stainless version today and now fondly recall why I felt so taken with this reference so many years ago.

I can’t think of many watches more classic and classy than the 5441. And since I happen to prefer a larger watch, the 42mm size is icing on the proverbial cake. 

Would love to hear your opinions about this watch. 





About the IWC Portugieser Ref. 5441

The IWC Portugieser represents one of the most enduring design languages in modern horology, tracing its origins to the late 1930s when two Portuguese businessmen commissioned IWC to create large, precise wristwatches using pocket watch movements. The Reference 5441, part of the contemporary Jubilee Portuguese collection, continues this legacy of oversized cases and railway track minute markers while incorporating modern manufacturing techniques and materials.

This particular execution showcases IWC's commitment to classical proportions and legibility, featuring the signature small seconds subdial at 6 o'clock and leaf-shaped hands that have become synonymous with the Portugieser line. The silver-toned dial provides exceptional contrast against the rose gold case, while the applied Arabic numerals maintain the collection's focus on functional readability. The manual-winding movement visible through this configuration speaks to the collection's historical roots in precision timekeeping rather than contemporary complications.

Within IWC's current portfolio, the Portugieser occupies a unique position as both an entry point to the brand's dress watch offerings and a sophisticated alternative to more ubiquitous luxury sports watches. The Reference 5441's classical styling and precious metal construction position it favorably among collectors seeking understated elegance, though it faces strong competition from similar offerings by Lange & Söhne and Glashütte Original in the German dress watch segment.

Super!

It is always a delight to see these movements in the Portugeiser series! It is far more beautiful than the newer inhouse movement (more romantic, perhaps? )

I agree, Cardio!

I loved your photos of the 5251 in Switzerland. The enamel dial is breathtaking! I also have one in my collection and will never part with it. Do you have other interesting IWC’s in your collection?

Thank you!

The photo of your 5251 is truly beautiful! I refer to this reference as a pocket watch on the wrist! This type is rare. I have a MR 5240 and a GST alarm; the rest are the older PDs. The GST is the ‘newest’ model I own (!).

And the movement on the 5251 may be even prettier than the 5441!
