02SERIES

As iconic as it is ironic.

Breakfast at Steffany’s.

We’re not saying this watch will get you sued by a certain luxury jeweller. But if it did, it’d be worth it. The 02SERIES Steffany Blue borrows the world’s most recognisable turquoise and gives it the Underd0g treatment: a pastel punch in the face, softened with clean lines, a sapphire sandwich dial, and a solid Swiss Sellita SW210-1 manual-wind movement. No date. No fluff. Just good taste, questionable behaviour, and a name that sounds suspiciously like someone you once matched with on Hinge.

Our playful twist

It wouldn’t be a Studio Underd0g watch without a playful twist. We’ve used current-day machining techniques and materials to create a sandwich dial like no other. The base dial features seven layers of custom-made Super-LumiNova pigment. Mounted on top of the base dial, is a 1mm sapphire disc, atop which the branding, minute track and Arabic numerals are printed. Once these two dials are affixed to one another via two slotted head pins, it creates a chunky dial with real depth.

The floating effect

In daylight, the printing details appear to float, casting a shadow on the lower base dial. As the watch moves around in relation to the light source, the shadows move accordingly. This results in a dynamic and ever-changing appearance.

Assembled in Great Britain

Studio Underd0g watches are Assembled in Great Britain, and undergo a full independent QC inspection before they’re shipped out from the UK thanks to our partners over at Horologium. The process includes demagnetisation, accuracy / rate review (3 positions) and regulation wherever necessary. A report card is included with every watch.

Shipping

Signed, sealed, delivered (and worth the wait)

We ship worldwide via DHL Express. Once your order is ready to ship you can expect an email from DHL directly with tracking and delivery information.

Shipping is free of charge for all watch orders.

Queries regarding shipping to the USA:
We will be shipping US orders ‘DDP’ (Delivered Duties Paid). This means you won’t face any unexpected duties or customs charges. Sales tax may be applied at checkout for some states where legally required.

Expanding the Studio Underd0g brand in the US is a key priority for us. Based on the current tariff regulations (as of Friday, Friday, 29th August 2025), we’ve decided to cover all tariffs and related charges for orders placed during the September 10th drop. We’ll review this approach for future releases, or if any significant changes occur, but for now, US customers won’t incur any additional fees after checkout.

We can’t refund any customs duties paid if you return your watch for a refund. We will deduct any duties, taxes or fees incurred by us from your refund.

Upon the import of your order to the US, Custom officials may request your Social Security Number / Tax ID. This is a request we are not able to override or avoid and if asked for, must be given in order to receive your shipment. Failure to do so will unfortunately lead to the shipment being returned to the sender and any shipping fees will unfortunately be made responsible to the customer.

Queries regarding shipping into Europe (Post-Brexit):
From January 1st, 2021 the United Kingdom (UK) is no longer part of the European Union (EU). We have adjusted the pricing to ensure EU customers will not be charged UK VAT (20%) on your order. We ship these EU orders on a DDU (Delivery Duty Unpaid) basis. This means that Local duties and taxes will need to be paid prior to delivery.

Queries regarding shipping to the rest of the world (not including USA):
