Tissott Limited Edition PRX 1853 Mineral glass based on the provided search results. Let me start by going through each webpage to see which ones are relevant. Webpages 1, 3, 8, and 9 all mention the "Limited Edition PRX 1853" with mineral glass. Wait, but in webpage 1, the brand is listed as "Tissott" which might be a typo for Tissot. The same applies to webpage 9. Those pages have similar content, including specs like 40mm dial, quartz movement, stainless steel strap, and 6-month warranty. Webpage 3 and 8 also list similar features but with different prices and warranty periods. Webpage 3 mentions a sale price of PKR 4,890 and a 1-year warranty, while webpage 4 talks about sapphire crystal glass, which is different.
