If you’re familiar with chronographs, you’ll know these were pretty cheap back then. In short, you can stop the seconds to measure short periods of time using the buttons. The subdials are attached to main hands, but can’t be used to measure time, as most pin lever calibers. Nonetheless, a cool piece of history in amazing condition. The OC 120 caliber inside is based on the Rego 153, with a beat rate of 18,000 and a 35-hour power reserve. It wears larger than it seems due to the square-ish case shape. **Condition:** Very good. Barely any markings on the case. Please see the pictures for a better description.  **Case Size:** 34 x 38.9, with a thickness of 13.3mm.  **Crystal:** Acrylic **Movement:** OC 120 (Rego 153), 18,000 bph, 35-hour power reserve. Service history is unknown, but everything is working as it should. **Other Information:** * Watch only, no box or papers. **Price:** Asking $120. Please add $15 for worldwide shipping. Payment methods include Wise, ACH transfer, Revolut, Bitcoin (On-Chain or Lightning), or PayPal G&S for buyers with solid references. Add +6% for currency conversion fees on the latter. I’m located in Portugal, but worldwide shipping isn’t an issue.  Established seller with over 220 transactions – buy with confidence!
