Other: This an incredibly rare opportunity to own a super cool and unique Nivada Travelmaster alarm watch - What a great name! In addition to a built-in mechanical alarm, it features a useful rotating bezel that allows the wearer to determine the current time in other major world cities at a quick glance. The 36mm steel case wears well on the wrist especially on what we believe to be its original Swiss NSA bracelet. In fact, this particular watch may even be a prototype given a variety of factors. Reference 87002 (for the silver dial variation) is present on the caseback and crossed over from the factory with a second reference number (87004) engraved below it. Nivada likely intended to put reference 87004 into production with a metallic grey dial, but we have yet to see another example in circulation. The unique Swiss NSA bracelet is signed by Nivada and came fitted on the watch as found - Even the spring bars appear to be original to the watch and will be included separately. The base AS 1568 mechanical alarm movement is properly signed by Nivada, but is missing its quick-set date provision (another sign of this watch being a pre-production prototype). Although the quick-set date button is non-functional, the date otherwise rolls over as it should. It's extremely satisfying to know that you won't run into anyone else wearing a Nivada Travelmaster - Once this one is gone, it's likely gone for good.
