Titus Vintage 17 Jewels - Incabloc
An elegant '50s-'60s Swiss classic in pristine condition, with an ETA 2390 heart!
Titus offered a simple elegance in the mid-20th century with its clean dial and robust Swiss movement formula. This piece, with its ETA 2390 caliber manual winding heart, original case back paper still attached, and refined dial execution, feels like a collector's-grade "time capsule." The condition seen in the photos is a display example, unworn.

Care & Usage Recommendations
A light oiling check and timer calibration are recommended before first wristwear (standard procedure after years of display).
The acrylic glass is easily polished with microfiber; if necessary, hairline scratches can be quickly removed with a Polywatch.
In daily use, it's important to be mindful of magnetic fields and water contact (snap-on cover).
