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. 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 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. My asking price is $1000 USD + shipping payment PayPal or Bank Wire.
