While generally this would be significantly too early for Steampunk (16th Century Germany) it’s such a marvellous combination of craftsmanship, brass and ingenuity that it sits perfectly alongside some of the more Victorian devices we’ve seen.  It’s a gunpowder flask, with brass and bone inlays, with a compass built into the centre and it can also operate as a pocket sundial!

The Watchismo Times will go into more detail (as they are very much timepiece experts) but I adore both the look and the aim to combine several different functions into one beautifully ornate work of practical art.  Thank you very much, Heresyoftruth!
