Introduction
The IWC Portugieser has long been the quiet intellectual of the luxury watch world—a dress watch that refuses to be delicate, a tool watch that shuns overt utility. With the reference IW501701, IWC Schaffhausen delivers a Portugieser Automatic 7 Days that distills the collection’s 1930s marine chronometer DNA into a thoroughly modern, everyday companion. The 42.3mm stainless steel case houses the in-house Caliber 52010, a movement that rewrites the rules of automatic winding with its ceramic components and seven-day power reserve. This is not a watch that screams for attention; it earns it through proportion, finish, and the quiet confidence of a manufacture that has been perfecting its craft since 1868.
Manufacture History
Founded in 1868 by Florentine Ariosto Jones, an American watchmaker who combined Swiss craftsmanship with American production methods, IWC has been synonymous with precision engineering and understated elegance. The Portugieser line debuted in 1939 as a wristwatch inspired by marine chronometers, featuring large, legible dials and high-performance movements. This heritage of clarity and reliability remains central to the brand’s identity, and the IW501701 is a direct descendant of that philosophy.
Movement: Caliber 52010
At the heart of the IW501701 beats the in-house Caliber 52010, an automatic movement that redefines what a week-long power reserve can be. The Pellaton winding system uses ceramic components—ratchet wheel, cam, and click—to reduce friction and wear, ensuring decades of reliable winding. The balance bridge is fully engraved, and the movement is decorated with Côtes de Genève and perlage. Despite its 7‑day reserve, the movement maintains amplitude stability through a specially designed spring barrel. The result is a movement that is both robust and beautiful, visible through the sapphire caseback.

Wrist Feel
On the wrist, the IW501701 is a study in balance. The 42.3mm diameter and 50.5mm lug‑to‑lug length sit comfortably on a 7‑inch wrist, with the lugs curving downward to hug the wrist. The 14mm thickness is noticeable but not cumbersome, thanks to the domed sapphire crystal and the gentle taper of the alligator strap. The weight is substantial—around 120 grams on leather—but never top‑heavy. The deployant clasp is well‑milled and secures the watch without digging into the skin. This is a watch that disappears during the day, only to remind you of its presence when you catch its blue dial catching the light.
Accuracy
In real‑world wear, the Caliber 52010 consistently runs within +2 to +5 seconds per day, well within IWC’s internal tolerances. The 7‑day power reserve means you can set it aside for a weekend and pick it up Monday with the time still accurate. The hacking seconds and quick‑set date are crisp and positive. Over a week of daily wear, expect deviation of no more than 10 seconds total.
Occasions
The IW501701 is versatile enough for formal events, daily office wear, dress occasions, and travel. Its 30m water resistance means it is not suitable for swimming or showering, but it handles hand‑washing and rain without issue. The lack of lume limits its utility in very dark environments, but the high‑contrast dial remains legible in most lighting.
Wrist Presence
4/5 – The blue dial and polished bezel catch light beautifully, but the overall design is restrained. It commands attention without shouting, making it suitable for boardrooms and dinners alike.
Reference Variants
The IW501701 is part of the IW5007 series. Other variants include the IW500705 (silver dial with gold hands), IW500704 (black dial with rhodium hands), and IW500703 (white dial with gold accents). The IW501701 stands out with its deep blue dial and stainless steel case, offering a modern yet classic look.
Family References
The IW5007 series includes references IW500701 through IW500705, all sharing the same case and movement. The IW5017 series (IW501701, IW501702) features the blue dial variant. Predecessors include the IW5001 series with the Caliber 5000.
Other Notable IWC Models
IWC’s lineup includes the Big Pilot’s Watch 43 (IW329301), the Portugieser Chronograph (IW3716), and the Pilot’s Watch Mark XX (IW328201). Each offers a different take on the brand’s aviation and maritime heritage.
Similar Watches
Jaeger‑LeCoultre Master Control Date offers a similar clean dial and in‑house movement. Glashütte Original Senator Excellence Panorama Date provides German precision with a large date window. A. Lange & Söhne Saxonia Thin is ultra‑thin and more formal, but with a hand‑finished movement that rivals the Portugieser.
Homages
No direct homage exists for the Portugieser Automatic 7 Days. The Steinhart Ocean One 39 is a budget diver homage, but not stylistically related.
Investment Value
The MSRP is $12,500, and pre‑owned prices range from $8,500 to $11,000. The trend is stable; this is not a limited edition, so it will not appreciate significantly. Buy for the watch, not as an investment. Auction history is minimal, with typical secondary market sales in the $9,000–$10,500 range.
Service Interval
IWC recommends service every 5 years. Authorized service centers are available worldwide, and independent watchmakers can also service the Caliber 52010, though parts availability may be limited. Approximate cost is $800.
Pros and Cons
Pros: In‑house Caliber 52010 with 7‑day power reserve; ceramic Pellaton winding system; classic, timeless design; high‑quality alligator strap and deployant clasp.
Cons: 30m water resistance limits swimming; no lume; thickness may be too much for smaller wrists; high price for a time‑only watch with date.
Final Verdict
The IWC Portugieser Automatic 7 Days IW501701 is a triumph of horological restraint. It offers a genuine manufacture movement with a week‑long power reserve, housed in a case that balances presence and wearability. For the collector who values engineering over flash, this is a watch that will reward daily wear for decades.
