IWC GST Alarm. At the pinnacle of IWC in 90s.
This particular piece is one example.
Integrated bracelet with fully adjustable links. Sandblasted titanium grade 2. Alarm function with blackened hand to make the red tip "floating". Black date windows for uninterrupted symmetry. Crisp, ultra legible hands and markers. Oversized crowns with sharp knurling for easy manipulation. Very unusual 50 meter WR with screwed down crown.
Function over form, seamlessly cool.
They don't make piece like this anymore.
