Hello, r/WatchExchange!  Today I am offering up a Vostok Komandirskie “Big Red One”.  This comes as the watch head on a navy third-party NATO strap. No box or papers or OEM band/bracelet. Asking $100 plus whatever shipping you select. The watch itself is in excellent, nearly-new condition with no hairline scratches I can see, and with the sticker on the back.  I believe it is a model 650840, and if so, the specs would be: * **Brand:** Vostok * **Series:** Komandirskie * **Model:** 650840 * **Movement:** Vostok 2415.01 (mechanical, automatic winding, overwind protection) * **Jewels:** 31 Ruby Jewels * **Case Size:** 41,6 x 49,6 x 15 mm  * **Weight:** 151 g  * **Case Material:** Stainless Steel  * **Case Shape:** Cushion  * **Case Back:** Solid  * **Band Material:** Stainless Steel  * **Band Width:** 20 mm  * **Shock-Resistant:** Yes  * **Water Resistance:** 200 m (20 ATM)  * **Functions:** Sensitive watch with a central second hand * **Dial Type:** Analog 12-Hour  * **Dial Color:** Red * **Luminescence:** Hands, Indexes * **Bezel:** Rotating  * **Average daily rate:** \-20+60 seconds per day * **The power reserve** duration from the spring's full winding is 31 hours.   I bought this at an estate auction so cannot speak to the provenance.
