## Description

Up for sale is a highly collectible, first-generation **SEIKO One-Push Chronograph (Ref. 5717-8990)**.

### Product Details

- **Brand:** SEIKO

- **Model:** Seikosha One-Push Chronograph

- **Reference Number:** 5717-8990

- **Movement:** Mechanical (Manual Winding), 21 Jewels

- **Features:** Chronograph, Date Indicator

### Condition & Functionality

- **Operation:** The watch is currently running, and the chronograph function starts, stops, and resets properly. 

- **Accuracy:** An overhaul (OH) was performed in 2020. However, it currently shows a noticeable time deviation (gaining/losing time). Since this is a vintage masterpiece over 60 years old, an overhaul is highly recommended for daily use.

- **Water Resistance:** Not guaranteed due to its vintage nature.

- **Dial:** The silver dial is in relatively good condition considering its age, with a beautiful vintage patina.

- **Case & Crystal:** There are minor scratches and signs of wear from normal use on the case and crystal. Please check the photos for details.

- **Caseback:** The engravings on the caseback are worn down due to age. The serial number is still readable, but other markings are difficult to discern.

- **Band/Strap:** Equipped with an aftermarket (non-original) stainless steel bracelet.

*Please review the high-resolution photos carefully to judge the cosmetic condition before purchasing. This item is sold as-is, suitable for vintage watch enthusiasts.*
