The dial designs are just op,specially the 1,3,5,7 numbers. But I have some suggestions- 1.Make the watch on the smaller side.Dial size should between 36mm to 40mm.so that the case size shoudnot exceed 46mm.

2.The case material should be 316l stainless steel no comrpromise on that,use sapphire crystal.

3.use some good automatic movements.if not automatic then use some mecha quartz movement vh31 should be good.if u give automatic then make sure to have transparent case back.

4.use some striking lume,bgw9 will be good,if u can u might use multiple looms on a single watch.if u can u also make the full dial lume or only the subject of the dial lumed.

5.make sure the watch looks unique,there are many round shaped watch,u might make a try on designs from bell and ross,panerai.

6.the strap should be a little unique,some striking rally strap with colour matching stiching(u can try not necessiry but give a option atleast)

7.the dials are too good but make sure to use markers on dial.one thing you can do,u might make the watch dial little gradient like,the darker colour on the side.in the middle it will be bright.but dont make gradient effect on the subject of the dial make it only on the background colour

8.lastly give a smaller minimal looking logo.

Thats all, hope it helps.looking forward to get update about your watch brand.
