Up for sale is my Sinn 103 automatic chronograph. From everything I can tell, this is an older 103 with fixed bezel that was widely popular in Japan, but seemingly not elsewhere. Service record indicates this is a 103.14100 (103.B.AUTO.POLY.TY). Includes last service record from 2008 in Japan. Keeps good time. Bracelet is sized for a 6.5 inch wrist with one extra link. Picked this up on r/WatchExchange this year. It has been a fun watch to wear but ultimately a little too big for me. Crystal is acrylic/polycarbonate so it can be polished with Polywatch and look fantastic. Wear and tear from likely 20 years of mild wear. Looks like it had a mild polish at some point in the past. Selling to reduce my collection and target a grail. * **Size**: 40mm * **Thickness**: 15.5mm * **Lug Width**: 20mm * **Crystal**: Polycarbonate * **Movement**: ETA Valjoux 7750 (automatic winding / 25 jewels / 28,800 vibrations) * **Power Reserve**: \~46 hours * **Water Resistance**: 20 ATM * **Magnetic Resistance**: 4,800A/m (DIN8309 compliant) * **Includes**: Watch, bracelet (important note: sized to 6.5mm wrist + 1 extra link only), service record, generic Sinn box * **Payment Methods**: Zelle, Paypal F&F * **Timestamp**: [https://imgur.com/pkMLKJH](https://imgur.com/pkMLKJH) * **More Info**: [https://sinn-japan.jp/product/103.b.auto.pol.ty/](https://sinn-japan.jp/product/103.b.auto.pol.ty/) **Price: $1100 or best offer**
