It is the Montblanc Meisterstück Platinum-Line Classique 145 with platinum-plated trim, which appears more modern and discreet compared to the classic gold variant. The designation "Platinium" on the Lufthansa page is a typo; correctly the model is called "Platinum". Collectors often advise against redeeming via the Lufthansa Worldshop, since the mileage conversion is economically unfavourable; anyone who has surplus miles anyway can however use the offer. A purchase from a specialist retailer has the advantage that the nib width can be tried out and individually selected there.
