R2450 means that the watch is priced at Two Thousand Four Hundred and Fifty South African Rand. This is quite a reasonable price for a luxury Swiss-made chronograph watch with advanced features like the Kotte & Co Blackmatic you asked about. Some other options in the search results that may interest you include the Tissot Couturier Chronograph for R12700, which is a Swiss chronograph from a renowned brand. Or the Casio Edifice models priced around R2379 - these have 100m water resistance and may suit your needs depending on your budget and preferences. Please let me know if you need any other details! I'm afraid I don't have pricing for the exact Kotte & Co watch in my database.
