More about IWC IW371903 Aquatimer Chronograph Titanium / Titanium

This is a titanium IWC Aquatimer Chronograph IW371903. It has an integral titanium link bracelet with a titanium double deployment clasp, and a scratch resistant sapphire crystal. There is a brushed screw-down solid case back engraved with "INTERNATIONAL WATCH CO. – AQUATIMER." It has a screw-down winding crown, and a round chronograph pushbutton at 2 o'clock. The crown at 4 o'clock operates the 60-minute unidirectional revolving bezel with a yellow 15-minute regatta count down scale located beneath the crystal (this crown also operates the chronograph reset button). The 42mm diameter solid three-body case, straight angled lugs, and flat bezel are polished/brushed. It has a black dial with luminous steel baton hands, a sweep center chronograph hand, and luminous minute/one-fifth second divisions and numerals. There are three black subsidiary dials, including a 12-hour totalizer at the 6 o'clock position, a running seconds dial at 9 o'clock, and a 30-minute register is at 12 o'clock. There are two rectangular aperture windows at 3 o'clock for the day and the date at 3 o'clock. It has a 44-hour power reserve at full wind, and it's water resistant to 120 meters/400 feet. The 14mm thick case, dial, and movement are all signed.
