The Suunto D9Tx is a compact dive computer that needs special tools and equipment to change the battery without compromising the seal integrity or damaging the delicate internal electronics. Our on-site technicians are all Suunto trained and certified for complete peace of mind.

We offer both drop-in and post in battery change options if you are unable to visit our London Store. We always advise getting your Transmitter Battery changed at the same time as the watch - that way you know you are all ready to go.

The turnaround for the Suunto D9Tx Dive Computer Battery Replacement is 5-7 days. We also offer a two-hour express service if you are really pushed for time - please note this is subject to availability so check with us before proceeding.

Please note that due to the deterioration of batteries and o-rings we can only use our own stocks of genuine kits to ensure you get the maximum life out of your battery and optimal seal integrity. Our kits are carefully monitored and rotated to ensure our stock is always fresh.

Please note that servicing products are excluded from the free UK delivery offer as we use a suitably insured next business day courier service to ensure your equipment is protected against damage or loss.
