1 in stock



Opus Mechan has been an industry leader in this type of pen! Utilizing authentic dials and watch parts from many movements. We painstakingly bend all the parts prior to putting them on the MOP/Abalone based barrels. All of this is done in house and by hand with our own proprietary process to ensure the highest quality barrels on the market today!

Another addition to this full-size pen is hand cast, machined, polished and set finials!

Every writing instrument is one of a kind and 100% handmade!

This writing instrument is setup as a fountain pen that has an OM fine point 18kt gold nib.  We always tune them prior to shipping to give you an incredible writing experience as soon as you receive it!

We can set it up as either a fountain pen or rollerball. Just pick your selection when you order the instrument. The rollerball option is $50.00 less.

This particular pen has an authentic Franck Muller dial in the barrel!

We pride ourselves on using only authentic watch parts for our Chrono and Steampunk Collection pens. We are NOT authorized dealers or representatives of the brand you see displayed on this pen! We do guarantee the authenticity of the watch dial and parts used in making this pen.
