Reference: 3506

Model: Ingenieur

Movement: Automatic

Year: Circa 1980s

Contents: Watch & Box

Case: The 34mm case is perfect. The SL was designed in the 80s because of the unpopularity of the larger-sized Ingenieur. However, it doesn't wear like a 34mm. It wears larger thanks to the integrated bracelet. The case is in great shape with normal signs of wear.

Dial: This dial is the one to have. Only done for the Reference 3506, the nickname comes from the grid pattern and slate grey color. The dial is in great shape with all the original lume still intact.

Strap & Buckle: The bracelet is tight and fits a little over a seven-inch wrist.
