Object description

Case and External Construction

The IWC Portugieser is constructed with a stainless steel case measuring 42mm. It is fitted with sapphire crystals on both the front and the case back.

The watch is presented on a strap described as alligator-grain leather with contrast stitching and features a fluted winding crown located at the 3 o'clock position.

Evidence for this section
  • “The 42mm size”
  • “The stainless steel case exudes durability”
  • “Enhanced by sapphire crystals on both the front and back”
  • “Fitted to a dark alligator-grain leather strap with contrast stitching”
  • “Fluted winding crown at the 3 o'clock case side”

Dial and Complications

The silver dial is accented with applied gold Arabic numerals, matching feuille hands, and a peripheral railway track. The display includes a small seconds subdial at 9 o'clock, a 7-day power reserve indicator at 3 o'clock with a red warning zone, and a date window at 6 o'clock.

The visible date aperture displays the number '23'.

Evidence for this section
  • “Silver dial with applied golden Arabic hour markers and matching feuille hands”
  • “7-day power reserve indicator with red low-reserve warning zone at 3 o'clock”
  • “Date display aperture at 6 o'clock reading '23'”

Mechanism and Documentation

The watch is powered by a 31-jewel automatic movement. Note that the source incorrectly identifies this as a 'chronograph movement'; the dial configuration lacks chronograph pushers or specific chronograph registers.

The watch is provided with its original box and card, and the production is dated to circa 2014.

Evidence for this section
  • “A 31-jewel automatic chronograph movement powers this timepiece”
  • “Circa 2014”

Open research questions

  • Does the serial number 3908578 align with the 2014 production date provided by the seller?
  • What is the actual caliber model associated with the IW500114 reference given the source's inaccurate description of a chronograph?
