Heuer Chronosplit Manuals
-- Please only fit good quality silver oxide battery brands such as Renata to both original watches & Rawsar modules.
-- Please keep your Chronosplit watches away from water and fluids as due to age, these watches are neither water-proof or water resistant.
-- When wearing your Chronsplit please be very careful and treat it gently especially if it is original as the original Heuer parts are very fragile. Full Rawsar conversions like the H1 & H2c module can however endure normal wear and tear.
-- Rawsar modules operate in the same way as the manuals above however battery life may differ.
