I picked up this IWC Ingenieur Chronograph Racer last month and man does this thing slap! I'm sure many of you have noticed and are very much aware of the partnership between Mercedes and IWC (you merely have to look at the analog clocks in your ride) so as the proud owner of a GL63 AMG, I simply had to pick once of these up to cycle through my collection. I also have another Ingenieur AMG but its currently being serviced. I decided to give it a themed photo shoot and I'd say it came out pretty well!

 

Since you indicate being a watch connoisseur, a question for you... Do you have any idea what Swiss company makes the Mercedes Benz collection watches? I've done a variety of Google searches, but find nothing specific. Side by side picture comparisons have me thinking the their are probably Tag Heuer derivatives...

 

IWC is the official partner of Mercedes, however other brands that have done collaborations in the past include: Breitling, Hublot, Tag Heuer, and Richard Mille. Hope this helps!

 

Updating this thread - in addition to the brands mentioned, MBUSA sold through its accessories catalog watches manufactured by Tourneau and some limited edition branded watches from Baume & Mercier.
