So far this is 5 pages of people giving you honest examples/reasons why being a watch trader is tough and the pitfalls you’ll face, along with first hand experience of new traders who started on this very forum and ended up being banned for unscrupulous practices. Then you telling people either they’re wrong or focussing in the negatives.
To take it back and start afresh to a degree, why don’t tell us what you’re high level Plan is?
How much capital are you setting aside?
Are you focussing on sales? If so vintage/used/new?
Will you sell high volume, low margin, unserviced into the trade or lower volume, higher margin by targeting buyers with money who have no experience of watches and are swayed by the experience and confidence buying from a dealer brings?
What value will you add?
Where will you source your watches?
What sales platform will you use? Online or B+M?
What are your thoughts on returns/after sales are?
Alternatively are you simply saying you’re going to be a collector who flips/sells a small number of watches a year, like many of us do, but formalises this on your tax return and with a limited company for the tax benefits? These are two hugely different things.
