Vintage form, with modern charm

We’ve used current-day machining techniques to emulate a mid-century vintage silhouette, while integrating a refreshingly modern dial. The varied size of the sub-dials is offset by the branding and movement details, which allows the chronograph seconds hand to pass through uninterrupted. Idiosyncratic, yet balanced.

The exclusive ST-1901B

Developed in partnership with Seagull, the ST-1901B is exclusive to Studio Underd0g. It features an all black main plate which beautifully frames the bridges, wheels and balance, as well as a silver swan neck regulator to allow for more precise regulation. All ST-1901B movements are regulated in Great Britain to -10/+15 seconds per day.

Incremental yes. Impactful, absolutely.

The 3rd Generation of the 01SERIES sees some incremental, but impactful improvements. The mid-case has been slimmed down, making the 01SERIES even more wearable at a total thickness of 12.9mm (down from 13.6mm). The crown thickness has been increased to guarantee a smooth winding action. The dial has been re-tooled and now features the ‘Assembled in Great Britain’ mark which is something few British brands can boast. We’ve also increased the size of the sapphire exhibition crystal to allow for better visibility of the new movement.

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. 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):

This means that any outstanding import duties, clearance fees, brokerage fees or any other additional charges are the responsibility of our customer and have to be paid on delivery of your order.
