Hi all, selling this Omega Triple-Date 3523.30 customized with Omega sourced guilloche panda dial from an 3623.33 and black bezel and hands. I received this watch on a trade and did not know much about it. Through Google searches I was able to track similar pieces to Tambo Watches. I confirmed via the serial number over email with Tambo Watches that this was a piece they did in 2017. Here is a link to a similar watch: [https://tambowatches.com/product/omega-speedmaster-triple-date-mk40-am-pm-guilloche-panda-build/](https://tambowatches.com/product/omega-speedmaster-triple-date-mk40-am-pm-guilloche-panda-build/). Previous owners have passed it off as some mysterious Omega boutique special or an unknown reference. But it is a custom piece by an independent watchmaker who specializes in Omega. This is for full transparency. It is a unique piece with the stunning 3623.33 dial that has a slight rose gold tint. Fully functional, and chrono features work as expected.  Measurements include a 38mm case size and 18mm lug width. Omega calibre 1151 movement. Asking for $1700, or best offer. Priced low to move and with the strange backstory in mind. Price includes shipping. US buyers preferred. Thanks!
