358

The Sinn 358 brings the brand’s aviation heritage into a contemporary, wearable package. Introduced as a modern evolution of Sinn’s classic pilot chronographs, the 358 distinguishes itself with a slightly larger 42mm case compared to the 356, offering enhanced dial legibility while maintaining the tool-watch ethos that makes Sinn a favorite among professional pilots and collectors alike.

Key variants include the 358 Sa Pilot and 358 Sa Flieger, both featuring Sinn’s signature sapphire crystal display back and 100-meter water resistance. The chronograph is powered by the reliable Valjoux 7750 automatic movement, prized for its durability and ease of service. Buyers should note that dial options—such as luminous Arabic numerals or pilot-style indices—affect both the watch’s visual impact and desirability on the secondary market.

Price variation typically comes down to dial configuration, condition, and whether the watch includes original box and papers. Earlier runs sometimes feature subtle differences in logo placement or lume color, which can matter to detail-oriented collectors. The 358’s value is also influenced by bracelet or strap choice; factory steel bracelets command a premium over leather. This model rarely suffers from aftermarket modifications, so focus on overall condition and completeness when evaluating examples.
