this is a bit difficult cause this Unitas with center second upgrade is VERY expensive... you will see Steinharts 1.500euro watch... and this is a very good price for a center second Unitas... but this price is only realiseable with this POOOOOOR Steinhart case, glass and dial (all made in asia). I saw so many case and glass... but this Steinhart case + glass is the most poor quality what i ever saw.
