In 1881, the Seiko company is established by K. Hattori, who manufactured clocks. The first Japanese wristwatch came to be in 1913. Since then, Seiko has seen considerable success, with their watch being the official timekeeper for numerous sporting events throughout the world, ever since the 1964 Tokyo Olympic Games. In fact, Seiko can also be said to have made the first quartz watch ever back in 1969.With every great company comes its fair share of copycats, and Seiko is no different. Many people attempt to replicate a Seiko watch in order to sell them at substantial discounts. Spotting a fake Seiko watch can be a simple enough task, luckily:The official Seiko web page will present its logo, showing you what kind of font it uses. This font is also used on the Seiko logo that is found on the dial of the watch. One kind of fake has an easily spotted error in that they sometimes misspell Seiko. Sometimes, they may use a font that is a little bit different than the official font. When in doubt, get a magnifying glass and carefully examine the font.Make sure the case back of the watch is proper, as well. More recent watches by Seiko come with a see-through sticker for protecting the case back. It will usually either transparent blue or clear. A fake watch will have a sticker but it will be transparent along with a single, thin red strip running down diagonally.The serial number behind the Seiko can be a giveaway. While copycats will be smart enough to include a fake serial number, they will not be smart enough to leave it at that; sometimes fake watches have the word Japan above the serial number. Seiko watches do not ever have this.On the back should be a logo of detailed, curved waves. A copycat might have a blurry, muddled wave shape and will very rarely feel like they are raised. A real Seiko has the wave logo raised.Look at the hands. The second, hour and minute hands should all be of the same color, which fakes do not very often accomplish.
There are many online shops that sell Seiko watches. Amazon.com is one of online shop that sells Seiko watches with any kind of models. You can visit www.amazon.com

I would stick with what the manufacturer put in the watch to begin with. If you don't know what kind or type of battery was in there I would not guess. I would Google the brand of the watch and or find the watch brand's website and look up the specifications to find the type of battery it takes.
The Fossil watch with the number BQ-9177 typically uses a CR2430 battery. To ensure the best performance and longevity, it's advisable to replace the battery with a high-quality lithium battery. If you're unsure or want to confirm, consult your watch's manual or a professional jeweler.
The best battery to use is the smallest watch battery possible. If that isn't exact enough use the type that were used to power the original tamagotchi.
Go to any depratment store,ask for a replacement and u will get a ticking watch again,trust me,i did it on my Fossil of the same exact kind I have the same Watch and the Battery info 373 SR916SW, I brought Energizer from Ebay and changed it myself.
