Quick answer
The Mark 17 is the IWC Pilot's Watch Mark XVII, sold from 2012 to 2016. It has a 41 mm steel case, a soft-iron inner cage, and a date arc at 3 o'clock. Replica versions copy the outline and dial layout. Case finish, movement, and lume differ by maker. No replica matches the original movement.
What the Mark 17 is
IWC released the Mark XVII in 2012 as the successor to the Mark XVI. Key specs:
- Case: 41 mm diameter, about 11 mm thick, stainless steel
- Movement: caliber 30110, based on ETA 2892-A2, 42-hour power reserve
- Dial: black, white numerals, triangle at 12, date arc with three windows at 3 o'clock
- Crystal: sapphire, antireflective coating on both faces
- Water resistance: 60 m (6 bar)
- Magnetic protection: soft-iron inner case
The date arc shows the current day plus the day before and after. IWC used this layout to keep the dial legible. Production ended in 2016 with the Mark XVIII.
What replica versions get right
Most replica Mark 17 watches match these points:
- 41 mm case diameter
- Dial layout with the triple-date arc
- Triangle marker at 12 and sword hands
- Solid caseback with engraving
Where replicas differ
Case thickness is a common gap. A genuine Mark 17 measures about 11 mm. Some replicas run 12 mm to 13 mm. The extra space comes from a thicker movement spacer.
The date arc is a second gap. Check that all three windows align on one horizontal line. Check that the fonts inside the windows match the dial numerals.
Lume is a third gap. Genuine models use Super-LumiNova. Replica lume may glow for a shorter time or with a different tone.
Crown threads and gasket fit affect water resistance. Most replicas are not tested to 60 m. Do not swim with one.
Movement options
Replica Mark 17 watches ship with one of three movements:
- Clone ETA 2892: 42-hour reserve, 28,800 vph, date function
- Miyota 9015: 42-hour reserve, 28,800 vph, thin build
- Asian 21-jewel automatic: lower beat rate, shorter reserve
Ask the seller which movement is installed. A Miyota 9015 has a smooth sweep and a known parts supply.
Checks before you buy
- Measure the case thickness if you can
- Confirm the date arc aligns
- Ask for a photo of the caseback engraving
- Confirm the movement name and beat rate
- Confirm the return window
