Buy offer Details

Dear Sir/Madam,
This is Joru Laka.
We are looking for products with the following specifications :
We intend to make a unisex quartz watch with two different case sizes, 36 and 41 mm. Also we want the case to made of 316L stainless steel, and have sapphire crystal glass. We would like our watch to be slim, classic and minimalistic, similar to Daniel Wellington.
Furthermore, we would like to use Swiss Ronda Movement for our watch. We are thinking of the Ronda Quartz 762 movement.
Finally, the most important feature of our watch is gonna be our exotic straps made out of fish leather (salmon and wolffish leather) from one the finest tanneries in Europe. We have already bought these leathers from a factory and would have them ready to be shipped to your factory if this is something your company have the capabilities to produce. These leathers are thin and would have to be sewed on top of a regular leather strap. (I can send you some pictures if you contact me). Thus, our questions are the following : would you be able to make such straps, and would you have any idea or estimates of the price of such services?
Really looking forward to hear from you!
Yours Sincerely Joru Laka
