Would you choose a 39 mm automatic watch with certified chronometer performance, or a bold 49 mm hand-wound model? The choice shapes comfort, timing evidence and daily habits. For another independent-maker comparison, see MSW My Swiss Watch vs Pilo Watches.

The MSW My Swiss Watch vs Formex decision involves two Swiss makers, but one model cannot represent either full collection. Here, Grandad's Line Vintage is the MSW reference, while Formex's Essence 39 Alpine White illustrates its technical offering. UK buyers should also confirm currency, VAT treatment, delivery charges and possible customs duty before paying. HMRC import guidance explains how charges depend on the goods and shipping circumstances.

The two listed prices are for different references, not equivalent watches, and are shown in Swiss francs rather than pounds. They offer a price snapshot, not a like-for-like value verdict. The MSW case and water-resistance details above apply specifically to Grandad's Line Vintage, not to every watch in our collections.
MSW My Swiss Watch

Best for: You may prefer MSW if you want a distinctive Swiss watch bought directly from its maker, with a documented long-term service arrangement.
Our collections serve different preferences, from bold, legible FIELD watches to rugby-inspired Flanker Sport automatic chronographs. For traditional mechanical horology, Grandad's Line Vintage has a 49 mm stainless-steel case, brown dial, black leather strap, sapphire crystal and hand-wound ETA 6498 movement. Its large format and daily winding ritual suit a buyer who wants a visually prominent, hands-on watch.
We were founded in Les Bois in 2017, and our watches are assembled in the Franches-Montagnes with local partners. Founder and CEO Denis Chappatte has more than 30 years of experience in watchmaking technology. This gives you a clear Swiss production context, although it does not substitute for a published accuracy rating for a particular movement.
Pros:
- Direct purchase from the Swiss manufacturer, with worldwide delivery and free standard shipping.
- Lifetime warranty and free lifetime maintenance, subject to the stated servicing conditions.
- Distinctive options, including a large hand-wound vintage model and rugby-inspired automatic chronographs.
Cons:
- Grandad's Line Vintage is a large 49 mm watch with 2 ATM water resistance, so it may not suit every wrist or wet daily routine.
- Lifetime support requires servicing every 60 months exclusively at MSW premises, a practical consideration for UK owners.
Formex

Best for: Formex may suit you if you favour a compact automatic watch with formal timing certification and stronger water resistance for everyday use.
The Essence 39 Alpine White is one example, not a specification for every Formex watch. Its stainless-steel case measures 39 mm, and it uses an automatic Sellita SW200-2 Power+ movement with a 65-hour power reserve. Formex states that each movement is COSC-certified. The model also has 100-metre water resistance and a case suspension system designed to flex with wrist movement.
At the time of checking, the listed price was CHF 1,570. This is higher than the CHF 960 shown for one MSW Grandad's Line listing, but the watches differ in movement, case size, water resistance and features. Compare exact references and the final UK checkout amount before deciding what represents value for you.
Pros:
- The Essence 39 example has a COSC-certified movement, giving you documented accuracy-testing evidence.
- Its 39 mm case and 100-metre water resistance make it the more practical of these two examples for a smaller profile and wet daily conditions.
- Formex states that the Essence 39 has a 65-hour power reserve and an adjustable bracelet clasp.
Cons:
- Its three-year warranty is shorter than MSW's conditional lifetime warranty and maintenance offer.
Which movement offers clearer accuracy evidence?
A chronometer certification gives you a clearer published indication of tested timekeeping performance than a movement name alone. Formex states that every movement in the Essence 39 example is COSC-certified. MSW's Grandad's Line specification names the ETA 6498, but does not state a daily-rate target or chronometer certification. That difference means Formex provides more explicit accuracy evidence for these examples, not proof that every Formex will outperform every MSW.
Formal certification also has a defined testing scope. The Swiss Federal Institute of Metrology describes a separate watch certification framework involving chronometric performance, water resistance, magnetic fields and power reserve, with independent monitoring. METAS certification requirements illustrate why a named standard is more informative than a general claim of precision. This is a separate certification framework, not a claim that either example has METAS certification.

What should UK buyers include in the total cost?
Free standard shipping does not necessarily mean a tax-free UK purchase. MSW offers worldwide delivery and free standard shipping, while faster delivery and shipping insurance may involve charges. Formex states that it ships worldwide with tracking and insurance, and its terms make tax and duty treatment dependent on the destination and checkout. Confirm whether VAT is collected at checkout and whether the courier may request payment before delivery.
For Great Britain, goods worth more than £135 may incur VAT and customs duty, with the duty rate depending on the item and its origin. Switzerland's trade arrangements and the watch's qualifying origin can affect duty, so do not assume a rate from the brand name alone. Which? cost guidance also explains that courier handling charges can affect the final amount. Check current UK rules and the exact checkout terms before ordering.
How should you choose between the two?
Start with the specific watch, not the brand label. If verified timing credentials and water resistance lead your priorities, the Formex Essence 39 example has the stronger documented case. If you value direct manufacturer purchase, distinct styling and long-term maintenance, MSW offers compelling advantages. Consider the 49 mm Grandad's Line Vintage only if its larger size and limited water resistance suit your habits.
Then compare the total cost, movement type, fit on your wrist and service arrangements. Ask whether you prefer an automatic movement that winds as you wear it or a hand-wound watch that requires regular winding. For a UK purchase, check any destination taxes, customs charges and return arrangements before payment.
Conclusion
For a first Swiss watch, MSW My Swiss Watch vs Formex comes down to your priorities, not a universal winner. Formex's Essence 39 offers stronger published timing evidence and water resistance, while MSW provides direct buying, distinctive designs and lifetime support under clear service conditions. If you value that maker relationship and long-term maintenance, MSW is our recommendation. Compare the precise reference, wrist fit and UK landed cost before ordering.

Frequently Asked Questions
Is Formex more accurate than MSW?
The Essence 39 example has a COSC-certified movement, while the published Grandad's Line specification does not state a chronometer certificate or daily-rate target. This gives Formex clearer documented accuracy evidence, not proof that every Formex outperforms every MSW watch.
Is MSW Grandad's Line suitable as a first Swiss watch?
It may suit you if you enjoy traditional hand-wound mechanics and a large, vintage-inspired design. Its 49 mm case and 2 ATM water resistance require careful consideration of fit and daily use.
How water resistant is the Formex Essence 39?
The Essence 39 example discussed here is rated to 100 metres. Other Formex models may have different specifications, so check the exact reference before using a watch in water.
Which brand offers longer-term warranty support?
MSW states a lifetime warranty and free lifetime maintenance, provided you arrange servicing every 60 months exclusively at MSW premises. Formex offers a time-limited warranty against mechanical and manufacturing defects.
Could there be extra charges when ordering a Swiss watch to the UK?
Yes, destination taxes, customs charges or courier handling costs may affect your final cost. Check the checkout details and applicable UK rules before completing your order.
