About the luminecense material that was used on many Roamers: quote from Wikipedia: “Promethium is a chemical element with symbol Pm and atomic number 61. – Practical applications exist only for chemical compounds of promethium-147, which are used in luminous paint “.
The green leather Morellato strap can be exchanged without charge with a new brown or black replacement. Lug width is 18mm. The watch is serviced and carries a 12 month warranty.
