Step-by-step guide to swapping your Torsk-Diver Pro onto an FKM rubber strap, covering spring bar removal, installation, and fit checks for the 43mm case.
Quick answer
To swap your Torsk-Diver Pro to an FKM rubber strap, use a spring bar tool to compress and remove the existing spring bars, then attach the new strap by seating one spring bar end into the lug hole, compressing the bar, and aligning the other end. Work over a soft surface and check that each spring bar is fully engaged before wearing.
Why FKM rubber suits the Torsk-Diver Pro
FKM rubber is a dense, flexible material that resists UV, saltwater, and sweat better than silicone or natural rubber, making it a practical choice for a 43mm dive watch. The custom FKM strap for the Torsk-Diver Pro is cut to fit the case and comes with a steel dive extension buckle, so you get a secure, integrated look without needing to modify the strap.
One trade-off: FKM is stiffer than silicone at first, so allow a short break-in period. Also, this strap is designed specifically for the Torsk-Diver Pro and will not fit the Torsk GMT 39.
Tools and prep before you start
You will need a spring bar tool with a forked tip (or a fine-tipped tool), a soft cloth or watch mat, and optional tape to protect the lugs. Work in a well-lit area over a table so small parts do not bounce away. If your watch has drilled lugs, a paperclip can help push the spring bar out, but a proper tool reduces the risk of scratches.
Step-by-step strap swap
- Remove the old strap: Place the watch face-down on a soft cloth. Insert the spring bar tool's fork between the strap and the lug, engage the spring bar's shoulder, and compress it while gently pulling the strap away. Repeat on the other side. Common mistake: prying against the lug instead of the spring bar, which can scratch the case. Check that both spring bars are fully removed and set aside safely.
- Attach the new FKM strap: Insert one end of a spring bar into the lug hole, then compress the spring bar with the tool and guide the other end into the opposite lug hole. The strap should sit centered between the lugs. Common mistake: not seating the spring bar fully, which can cause the strap to detach. Tug gently on the strap to confirm the spring bar is locked in place.
- Adjust the buckle and fit: Thread the strap through the steel dive extension buckle and adjust to a snug fit that allows a finger to slide under. The cut-to-fit design means you may need to trim excess strap length if it is too long; trim only after confirming the fit. Common mistake: cutting too much length at once—start conservatively. Test the buckle closure and ensure the strap tail is secure before diving or swimming.
