Watch w/ A fish logo on the winder?

Wondering what IWC watch, which collection, has a fish logo on the dial? I have a friend has a perpetual calendar that has this logo...Just wanted to know more about it. His is stainless steel I believe. Thanks

Welcome to the forum.

The "fish icon" on the crown was used by IWC to denote water resistance in an IWC timepiece. It was used across several lines, if not all of them. In my collection, I have several watches with "fish icons" such as Portuguese Chronograph, Portuguese Perpetual Calendar, Classic Pilot's Double Chronograph, Aquatimer, and GST Perpetual Calendar in. Steel on Steel bracelet. IWC stopped using the "fish icon" in the mid 2000s.

Does your friend's IWC Look like this?

The GST Perpetual Calendar is a great, complicated, durable sports watch. It has a 31 jewel, automatic movement with IWC perpetual module with a 4-digit year display, moon phase and accounts for leap year. Also, it has a chronograph.

Thanks it does look like that. I was wondering which watch it actually was! this helps a ton. Thanks so much.

Hi Ardoise.

I have an aquatimer 1884. It was given to me by an uncle around 20+ years ago.
Never wore it. It is now in need of maintenance and refurbishment. It has the fish logo on the winder. I took it to an iwc shop and they could not identify the year or any details about it.
I am interested in knowing about this watch.

Hi there
Can you please post a picture of your uncle's watch to aid in our identification.

We love seeing watches that are gifts from uncles, but "1884" does not refer to an Aquatimer I'm familiar with.
