Creating a Braun BN0171 Watch SVG animation

codeswaps profile image CodeSwaps ・Updated on ・8 min read

In this tutorial our goal is to create a Braun BN0171 Watch SVG animation starting from a Sketch file resource. We will look at how to extract and optimise the SVG for web, how to add the necessary CSS, and finally how to bring this to life with a sprinkling of JavaScript. It’s just for fun, but often I find making things fun to be the best way to learn things.

OK let's begin

To start with we are going to download this resource:-

https://www.behance.net/gallery/64303683/Braun-Watch-Free-Vector-Resource

Extracting the SVG and optimising it for web

When we export an SVG from Sketch it outputs a lot of extra guff we don't really need.

Open up your SVG in a code editor and you will see something like this at the beginning (plus a lot of unnecessary ID's):-

<?xml version="1.0" encoding="UTF-8"?>
<svg width="403px" height="776px" viewBox="0 0 403 776" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <!-- Generator: Sketch 62 (91390) - https://sketch.com -->
    <title>Group</title>
    <desc>Created with Sketch.</desc>
Enter fullscreen mode Exit fullscreen mode

We don't need all that extra stuff so we're going to use a tool to clean this up. I recommend optimising your SVG code using something like https://jakearchibald.github.io/svgomg/

My method was to extract certain things separately like the time indicators. The end result html was:-

All we need to do then is identify the hour, minute and second hands and add the correct classes. I recommend inspecting the html in Chrome dev tools for this part.

Adding styles

Now we can style the SVG with CSS. The trickiest part was getting the transform-origin right which took a bit of trial and error. Also notice a nice trick with filter: drop-shadow which works much better than box-shadow in this case.

body {
  font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol";
  background-color: #FFCC00;
}

.container {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 776px;
  margin: 0 auto 100px;
}

.watch {
  width: 403px;
  position: relative;

  &-logo {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-28px, -70px);
  }

  &-face {
    position: absolute;
    width: 359px;
    height: 359px;
    top: 208px;
    left: 19px;
  }

  .hours {
    position: absolute;
    left: 50%;
    top: 88px;
    transform-origin: 48% 105%;
    filter: drop-shadow(1px 1px 0 #999999) drop-shadow(0.11rem 0.11rem 0.13rem rgba(0, 0, 0, 0.95));
  }

  .mins {
    position: absolute;
    left: 49%;
    margin-left: 2px;
    top: 45px;
    transform-origin: 48% 103%;
    filter: drop-shadow(1px 1px 0 #999999) drop-shadow(0.11rem 0.11rem 0.13rem rgba(0, 0, 0, 0.95));

  }

  .secs {
    position: absolute;
    left: 48%;
    top: 50px;
    transform-origin: 49% 84%;
    filter: drop-shadow(1px 1px 0 #f3dc7c) drop-shadow(0.11rem 0.11rem 0.13rem rgba(0, 0, 0, 0.95));
  }
}

Bringing it all to life

The final step was to bring this to life keeping the JS to a minimum we come up with:-

var inc = 1000;

clock();

function clock() {
  const date = new Date();

  const hours = ((date.getHours() + 11) % 12 + 1);
  const minutes = date.getMinutes();
  const seconds = date.getSeconds();

  const hour = hours * 30;
  const minute = minutes * 6;
  const second = seconds * 6;

  document.querySelector('.hours').style.transform = `rotate(${hour}deg)`
  document.querySelector('.mins').style.transform = `rotate(${minute}deg)`
  document.querySelector('.secs').style.transform = `rotate(${second}deg)`
}

setInterval(clock, inc);

And that's it! Hope you enjoyed this little write-up.

Final Result

ps, the designer seemed to think there were 72 seconds in a minute so I had to omit the secondary indicators on the watch. :(
