    I had an incredible experience with Bo! I’ve been waiting and hunting for a Panerai 243 since 2018; when this full kit came up, I had to get it!

Frequently Asked Questions

What is the IWC Ingenieur Automatic 40 IW328903 green grid dial?

The IW328903 is the 40mm Ingenieur Automatic with a green grid-pattern dial, released in 2023 as part of IWC's relaunch of the Gerald Genta-designed Ingenieur. It features an integrated steel bracelet and references the 1976 SL Ingenieur.

What is the history of the IWC Ingenieur?

The Ingenieur was created in 1955 as an antimagnetic watch for engineers, and in 1976 Gerald Genta redesigned it with an integrated bracelet and screwed bezel. The 2023 relaunch returns to the Genta design language with modern in-house movements.

What movement powers the IWC Ingenieur Automatic 40 IW328903?

The IW328903 uses the in-house automatic Calibre 32111 with a 120-hour (5-day) power reserve, visible through the display caseback. It carries a soft-iron inner case for antimagnetic protection consistent with the Ingenieur's original purpose.
